SELECTION
(a) Service Factor
Calculate Speed Ratio by dividing the rev/min of the faster shaft by the rev/min of the
slower shaft.
(b) Service Factor
From Table 3 (page 39), select the Service Factor which is applicable to the drive. If the
drive is speed increasing, an additional factor may be required – refer to top of Table 3.
(c) Design Power
Multiply the normal running power or prime mover power by the Service Factor. This
gives the Design Power which is used as the basis for selecting the drive.
(d) Belt Section & Type
Refer to Table 2 (opposite) and trace to the right along the horizontal axis to the rev/min
of the faster shaft. Trace upwards along the vertical axis to the Design Power. Choose
the belt section and type represented by the area in which the point of intersection falls.
(e) Minimum Pulley Diameter
Refer to Table 1 (below) and select the minimum recommended pulley, using the Design
Power from step (c) and the faster shaft speed. This is a guide to the minimum pulley
pitch diameter capable of transmitting the design power at the given speed,without
generating excessive bearing loads.
(f) Pulley Pitch Diameters
Refer to the drive selection tables on pages 40 to 51 and for the belt section chosen
read down the speed ratio column to the value nearest the calculated speed ratio. Use
the Minimum Pulley Diameter from step (e) as a guide to the small pulley selection.
(g) Belt Length, Centre Distance and Correction Factor
The drive tables list ISO belt lengths.
Along the same line as the chosen Speed Ratio read across the table to find a suitable
Centre Distance. The required Belt Length is given at the head of the column.
Note the Correction Factor by following the colour band in which the chosen centre
distance falls, to the top of the table.
If the Centre Distance is not specified consider a drive with a centre distance
approximately equal to the sum of the pulley pitch diameters.
When non-standard pulleys or belts are used the Centre Distance and Belt Length can
be calculated using the formulae given on page iii of the technical information section.
Interpolate from the tables for the Correction Factor.
(h) Basic Power per Belt
Refer to the power rating tables (pages 52 to 61) for the section and type of wedge belt
chosen. In the left-hand column locate rev/min of the faster shaft, i.e. the one with the
small pulley. Read across to the column headed by the pitch diameter of the small pulley
and note the rated power.
For CRE Plus belts refer to page 56 for power ratings.
Note that Fenner pulleys are designed for belt speeds up to 40 m/s. If using non-Fenner
pulleys seek manufacturer's approval at high speeds.
N.B. The powers listed in the columns headed by the motor speeds in the Drive Tables
(pages 40 to 51) give the power per belt including Speed Ratio Increment, step (j), for
Ultra PLUS wedge belts. These powers require correcting for belt length and arc of
contact correction factor (g) and should be used in conjunction with the appropriate
Service Factor.
(j) Speed Ratio Power Increment
From the power rating tables (pages 52 to 59) note the additional power per belt for the Speed
Ratio being used.
This value is the same for all types of belt of a given section.
(k) Corrected Power per Belt
Add the Speed Ratio Power increment (j) to the Basic Power per Belt (h) and multiply by the
Correction Factor from step (g).
(l) Number of Belts required
Divide the Design Power from step (c) by the Corrected Power per Belt (k). The result gives the
number of belts required. If the answer contains a fraction use the next whole number.
(m) Bore sizes
Check that the pulleys will fit shafts by referring to the pulley dimension tables (pages 62 to 69).
* This table is intended as a guide to selection only. Bearing loads should be carefully considered when using small pulleys on electric motors. This is particularly
important when using the small pulleys allowable with CRE PLUS or Quattro PLUS belts.

REV/MIN OF FASTER SHAFT
DESIGN POWER kW
FEN01/14 : DRIVE DESIGN & MAINTENANCE MANUAL 39
EXAMPLE
Design a wedge belt drive from a 50 kW 6 cylinder diesel engine which runs at
1050 rev/min to a reciprocating compressor running at 660 rev/min. The centre
distance is to be approximately 1600 mm and the duty is 24 hours/day. The engine
shaft is 70 mm diameter and the compressor shaft 80 mm diameter.
(a) Speed Ratio
Speed ratio = 1050 = 1.59:1
660
(b) Service Factor
From Table 3 the service factor is 1.4.
(c) Design Power
= 50 x 1.4 = 70 kW
(d) Belt Section
By referring to Table 2 (opposite) the intersection of design power and the speed of
the faster shaft indicates SPB or QXPB section.
(e) Minimum Pulley
From Table 1 (page 38) the minimum recommended pulley is approximately 250 mm.
(f) Pulley Pitch Diameters
By referring to the centre distance tables relating to SPB section belts on page 47
the selection is a driving pulley of 315 mm pitch diameter and a driven pulley of
500 mm pitch diameter.
(g) Belt Length, Centre Distance and Correction Factor
Reading across the table, the nearest centre distance to the 1600 mm required
is 1607 mm. The belt length at the head of the column is 4500. By following the
colour shading to the top of the table, a correction factor of 1.05 is noted.
(h) Basic Power per Belt
From the power rating table (pages 52 & 61) by interpolation the rated power/belt
for a 315 mm pitch diameter pulley at 1050 rev/min is 18.94kW for Ultra PLUS SPB
(22.37 for Quattro PLUS QXPB)
(j) Speed Ratio Power Increment
The power increment (by interpolation) for a speed ratio of 1.59 at 1050 rev/min is
0.77 kW. (pages 58)
(k) Corrected Power per Belt
= (18.94 + 0.77) x 1.05
= 20.7 kW per belt. (24.3 for QXPB)
(l) Number of Belts required
= 70 = 3.38 i.e use 4 SPB Ultra PLUS wedge belts.
20.7
or
= 70 = 2.88 i.e use 3 QXPB Quattro PLUS belts.
24.3
(m) Bore Sizes
From pulley dimension tables, a 315mm x 4 SPB has a bush size 3525 with 100 mm

Type 6NR pulleys are made to catalogue dimensions, but modern manufacturing techniques result in there being no recess behind the Taper Lock bush, the J dimension is then approximately equal to the
small diameter of the Taper Lock bush.
Dimensions in millimetres unless otherwise stated. *Non-preferred pulley sizes. Pitch diameters in italic type indicate pulleys to be used with Z V-belts, XPZ & QXPZ wedge belts only.
All envelope, prime functional and Taper Lock bush dimensions are correct at the time of publication. Non-functional dimensions may vary slightly.
These pulleys are designed to operate at rim speeds upto 40m/sec, for higher speeds contact your local authorised distributor.

PowerTwist PLUS belting incorporates the most up-to-date materials available, giving it unique qualities of resistance to many of the adverse working
conditions that belts are subject to, and properties that were deficient in earlier designs of link belts. These link belts are complementary to the range of
Fenner wedge and Vee Belts and are extensively used in industrial, marine, agricultural and heating & ventilation applications.
Advantages of PowerTwist PLUS Link Belts
Adjustable to any length, adaptable to any drive
Fit the belts to the drive, not the drive to the belts.
Drive elements can be located most effectively and belts installed without
removing bearings.
No Slippage
Quick, easy length adjustment minimises belt creep to guarantee
full speed and full productivity of machines.
Minimum Inventory
Four boxes of link belting can replace hundreds of fixed length, endless V-Belts.
Boxes can be stored easily, providing simplified visual control of inventory.
Vibration
Fenner link belts are manufactured to extemely close tolerances.
The design of the belt significantly reduces transmissible vibrations
in some applications.
Long Lasting Construction
The extreme flexibility of these belts greatly reduces belt stress, heat build up and
fatigue. The construction of the belts is designed to dissipate heat.
Maximum Power Delivery
On multiple belt drives it is easy to maintain correct tension on all belts. Each belt
carries its required load, for maximum power delivery and longest life.
Temperature
Power Twist Plus will operate in temperatures from - 40 to 110OC.
Water, Chemical & Oil Resistance
This belt will not degrade if immersed in water or if in contact with oil, grease,
agricultural chemicals and common solvents.
Economical Lengths
PowerTwist belting is also available in economical lengths.
Boxed in 10 metre lengths, ideal for display or mobile maintenance engineers.
Special Types
Double V Section
For use on serpentine drives with both sides of the belt engaging in V pulley
grooves.
AA; BB & CC sections.
Ground Round
Designed specifically to replace round profile rubber or leather belts on "rope"
drives.
8mm, 9.5mm, 12.5mm, 14mm & 19mm diameters.
High grip, or PTFE top layer coatings available for conveying applications.

PowerTwist Plus link V-Belts are manufactured from an exclusive, high
strength urethane/polyester composite. This makes PowerTwist Plus an
incredibly strong, yet flexible belt that will take on the roughest of working
conditions.
PowerTwist Plus V-Belt's unique cross-lock design gives a raw edge cog
construction which provides excellent durability and performance, delivering
higher power ratings than almost any other link type V-Belts on the market.
When the tension is applied to the belt, the cross-link design locks tightly thus
producing the lowest stretch of any link V-Belt.
PowerTwist Plus V-Belts save time on installation because no special tools are
required, all that is needed is a quick twist both to couple or uncouple the belt
and this is easily achieved in seconds.
Available from stock in Z, A, B and C sections, for use in standard dual groove
pulleys. See pages 62-69.
Selection
To design a Fenner Power Twist Plus drive simply refer to the wedge belt selection procedure (pages 38-39) utilising the power ratings given above.
For applications that would benefit from the advantages of modern link belting, but require SP (wedge) type belt ratings, consult your local Authorised Distributor.

DIMENSIONS OF LP ADJUSTABLE PULLEYS
General
The LP adjustable pulley is used in conjunction with
standard Taper Lock dual groove pulleys, pages 62-69,
and Fenner Classic V-belts to allow small adjustments
to driven speed from fixed speed prime movers.
Construction
Made from grey cast iron, these pulleys have one
fixed flank, and an opposite flank which can be
adjusted by screw thread, with the drive stationary,
and then fixed in position.
Installation and Use
Pulleys are supplied pilot bored for reboring/
keywaying as appropriate.
Drive centre distance adjustment is used to
maintain correct belt tension if pulley diameter is
changed.
Note that the belt centre line shifts when diameter
changes. Driven pulley may need realignment.
Bores are to F7 limits, Dimensions in millimetres.
* Stock pulleys are minimum bore without shaft grub screw holes. They can be supplied bored to size with tapped holes on request.
For other than smooth load 10 hours per day applications, the above powers should be derated by 25%.
Bi-Loc Pulleys
The Fenner Bi-Loc system employs lightweight
cast iron pulleys with 'Quadruple Duty' Grooves
for A/SPA and B/SPB section belts. Twin-tapered
steel bushes with metric and Imperial bores
are used to mount single, double or different
diameter pulleys on one shaft. A shrunk-on fit
is achieved without keys or grub screws. Only a
spanner is needed for fitting and removal.
Mount single, double or different diameter
pulleys on one bush.
Use retainer and screws for single pulley
assembly.
Use bolts for double groove pulley assembly.

"One-Shot" Tensioning
Fenner belts are Precision Built to ensure inherent
length stability and matching during storage and on the drive.
Over many years, the principle of "one-shot" tensioning has
been verified by successful drives the world over.
Install the belts to be a snug fit around the
pulleys.
Spin the pulleys 3-4 revolutions to bed belts into
the pulley grooves.
(Note: if done manually, beware of finger entrap-
ment between belts and pulleys)
Tension the belts to the 1.25x setting forces
from the table.
Run the drive under load for 15-20 minutes.
Stop the drive, check tension & reset to the basic
value (standard V and wedge belts) if necessary.
CRE PLUS & Quattro PLUS belts should be reset
to the 1.25x value.
With a drive that is properly designed for the application
there should be no need for further attention during the
life of the belts.
For short centre distance drives where the deflection of the
belt is too small to measure accurately it is recommended
that both deflection and setting force be doubled.
Method of belt tensioning using Fenner Belt
Tension Indicator
Calculate the deflection in mm on a basis of 16mm
per metre of centre distance. Centre distance (metres)
x 16 = deflection (mm).
Set the lower marker ring at the deflection distance
required in mm on the lower scale.
Set the upper marker ring against the bottom edge
of the top tube.
Place the belt tension indicator on top of the belt at
the centre of span, and apply a force at right angles
to the belt, deflecting it to the point where the lower
marker ring is level with the top of an adjacent belt.
Read off the setting force value indicated by the top
edge of the upper marker ring.
Compare this force to the kgf value shown in the
table.
If a Fenner Belt Tension Indicator is not available, a
spring balance and rule will suffice.
NOTES:
For single belt drives a straight edge should be placed
across the two pulleys to act as a datum for measuring the
amount of deflection.
If the measured force falls within the values given,
the drive should be satisfactory. A measured force
below the basic value indicates under-tensioning.
A new drive should be tensioned to the 1.25x value
to allow for the normal drop in tension during the
running-in period.
After the drive has been running for 15–20 minutes,
under load the tension should be checked and re-
adjusted, if necessary.
Troubleshooting
Small radial cracks on belt side and base
Generally caused by slippage due to insufficient belt
tension, but excessive heat and/or chemical fumes
can also cause the same problem.
Belt swelling or softening
Caused by excessive contamination by oil, certain cutting
fluids, water or rubber solvent.
Whip during running
Often caused by incorrect tensioning, particularly
on long centre drives. If a slightly higher (or lower)
tension does not cure the problem there may be
a critical vibration frequency in the system which
requires re-design or use of banded belts. Consult
your local Authorised Distributor Technical Services.
Pulleys
Pulley groove wear can cause rapid belt failure.
Check grooves for wear with a Fenner groove gauge.

within one third of the centre distance from the small
pulley.
The tensioning pulley must have at least the same
diameter as the small pulley of the drive.
Tensioning pulley movemement must allow for
passing the belts over the outside diameter
of one of the drive pulleys on installation, and
should also allow for belt stretch/bedding in.
The modern wedge belt drive is a highly
efficient power transmission medium, but
optimum performance will not be achieved
without correct tension and alignment.

Taper Lock
All Fenner V and wedge belt pulleys use Taper
Lock shaft fixing.
Detailed instructions for fitting and dismounting
Taper Lock products are included with Taper Lock
bushes.
Although comparatively old in principle today's belt
drive is an extremely efficient method of transmitting
power between prime mover and machinery.
It owes its present high performance standards
to many years of research and development by
engineers and technologists, leading to significant
refinements in materials and processes.
To derive maximum benefit from such advances it is
important that the simple installation and operation
procedures set out here are closely followed. Making
these routines standard practice will ensure optimum
performance and long, trouble-free life from Fenner
belt drives.
Installation
PULLEYS
Before assembling the drive, check the pulley
grooves are free from scores or sharp edges, and
all dimensions conform to the relevant standard.
Drive installation is straightforward with Taper
Lock – but follow all steps on the installation
leaflet provided with every Taper Lock bush.
ALIGNMENT
Good alignment of pulleys is important to avoid
belt flank wear. The diagrams opposite show
some of the common alignment faults.
Pulley misalignment should not exceed 1/2°
angular and 10mm / metre drive centre distance,
axial.
A laser alignment device is available, which
facilitates quick, easy and accurate pulley
alignment - consult your local Authorised
Distributor.
BELT INSTALLATION
When the pulleys have been correctly positioned
on the shafts, the belts can be installed to complete
the drive.
The drive centre distance should be reduced
prior to the installation of the belts so that they
may be fitted without the use of force. Under
no circumstances must belts be prised into the
grooves. Belts and pulley grooves can easily be
damaged by using sharp tools to stretch the belts
over the pulley rim.
The installation allowance given in the table
opposite is the minimum recommended reduction
in centre distance for the various belt sections
and lengths to allow for correct fitting.
The take-up allowance given in the same table
should be added on to the calculated centre
distance to allow for belt stretch/bedding in.
GUARDS
Where guards are necessary it is desirable to use
mesh materials to permit adequate ventilation.
Guards should be generously sized to allow for
incidental belt flap.
TENSIONING PULLEYS
If tensioning (jockey) pulleys are to be used on wedge
belt drives, they must be grooved pulleys working on
the inside of the drive, preferably on the slack side.
The pulley should be positioned as close as possible
to the large pulley. Flat tensioning pulleys, bearing on
the outside of the drive are permissible only with V
and not with wedge belts. They should be positioned

1. How to Measure
Correct way to measure:
PowerTwist Plus – end of tab to first empty holes (right to left, above)
2. Assembly - PowerTwist PLUS
Pitch Length
Determine the required pitch length of the belt. Measure PowerTwist Plus from the
second empty hole on the last link to the end tab. Subtract one link in every 24 for
Z, A, B sections, one link in every 20 for C section. For multiple belt drives, count
the number of links in the initial belt and make additional belts the same number
of links. Lay the original belt on a table and lay the additional belts side by side to
ensure the correct length and matched sets.
3. Installation
Make PowerTwist Plus belts to the correct pitch length and then install
them as you would an endless belt.
1. Move motor to reduce centre distance.
2. Place all belts in correct position.
Where it is necessary to thread belts through confined spaces, or around shafts
without moving bearings, it is possible to make the belts "in site". Some reduction
in pulley centre distance is still necessary for ease of assembly.
3. Move motor back into position, applying correct tension.
4. Secure motor tightly.
Method of Belt tensioning using Fenner Belt Tension indicator
1. Calculate the deflection distance in mm on a basis of 16mm per metre of span.
Centre Distance (m) x 16 = Deflection (mm)
2. Set the lower marker ring at the deflection distance required in mm on the lower scale.
3. Set the upper marker ring against the bottom edge of the top tube.
4. Place the belt tension indicator on top of the belt at the centre of span, and apply a
force at right angles to the belt deflecting it to the point where the lower marker ring
is level with the top of an adjacent belt*.
5. Read off the force value indicated by the top edge of the upper marker ring.
6. Compare this force to the kgf value shown in the table opposite.
7. If a Fenner Belt Tension Indicator is not available, a spring balance and rule will suffice.
CAUTION
When properly installed, initial tension may appear excessive.
Tension drops to normal when drive begins to run.
4. Retensioning
It is important to retension all drives after an initial run-in period. On fixed
centre drives, it may be necessary to remove a link from each belt for proper
retensioning.
Always work with the belt inside out, tabs
pointing outward Place end tab through two links at once. Flex belt further and insert second tab
through end link by twisting tab with
thumb.
Ensure tab returns to position across belt.
Reverse belt so tabs run inside.
5. Disassembly - PowerTwist PLUS
Turn belt inside out with tabs pointing
outwards. Bend back as far as possible;
hold with one hand. Twist one tab 90º
parallel with slot.
Pull end of link over tab. Rotate belt end with tab at 90º to line of
belt.
Pull belt end through two links.

Effective belt lengths are used with pulley effective diameters in all centre distance
calculations.
All the above belts can be supplied with rib numbers of at least 40.
Intermediate belt lengths are available - consult your local Authorised Distributor.
Belts may be designated by: number of ribs, section letters and effective length in mm
(e.g. 16 PL 2235)
80
Necessary drive data: Driving/driven shaft speeds (rev/min), absorbed drive power and/
or motor power (kW), type of prime mover (inc. electric motor starting arrangements)
and driven machine, machine shaft diameters (mm or ins.), required drive centre
distance (mm), any other dimensional constraints.
(a) Service Factor
Select the service factor applicable to the drive from table 1 below. For a speed increasing
drive multiply the basic service factor by the special factor in the top left box to achieve
the full service factor.
(b) Design Power
Multiply the normal running (absorbed) power of the drive, or if not known, the motor
power, by the service factor (a), to give the design power which is used as the basis for
drive selection. This power should be calculated in kW.
(c) Ribbed Belt Section
Refer to table 2, page 81 and find the point of intersection of the faster drive shaft speed
in rev/min, and the design power
(b). This point will indicate required belt section and approximate small pulley diameters/
rib numbers.
NOTE: PK section ribbed belts are normally used for automotive applications. For general
industrial applications PJ, PL or PM section belts should be selected.
(d) Speed Ratio
Divide rev/min of faster shaft by that of the slower shaft to give required speed ratio.
(e) Minimum Small Pulley Diameter
Refer to table 5, page 81 to find the minimum recommended small pulley diameter,
using design power (b) and the faster shaft speed.
(f) Pulley Effective* Diameters
Refer to table 6, page 82 to select pulley effective diameters giving close to the required
speed ratio (d), using (e) as a guide to small pulley diameter.
Calculate the exact speed ratio and check acceptability
* Note: All pulley designations show effective (outside) diameters. Exact speed ratios are
calculated using pitch diameters,– see under table 6, page 82.
(g) Belt Length and Centre Distance
Use the formulae below to establish which standard belt length (listed page 79)
gives closest to the required drive centre distance.
(h) Combined Correction Factor
Refer to tables 3 & 4, page 81 to find power correction factors for belt length
and for the arc of contact for the small pulley (the latter calculated using pulley
diameters D & d, and centre distance C - all in mm).
Multiply these two factors together to give the combined correction factor.
(j) Basic/Additional Power per Rib
The main power rating tables on pages 82 & 83 show basic power per belt rib, in
kW, at the intersection of faster shaft speed (LH column, in rev/min) with pulley
diameter (across top, in mm). Additional power per rib due to speed ratio is shown
in the smaller RH table. Values for shaft speeds not listed can be derived by
interpolation.
(k) Corrected Power per Rib
Add the speed ratio increment to the basic power per rib (j) and multiply the the
resultant kW value by the combined correction factor (h) to give the full power per rib.
(l) Number of Ribs Required
Divide design power (b) by the full power per rib (k) to give the number of belt ribs
required. Round up to an even number and check whether standard pulleys are available.
(m) Pulleys
When pulley specification is established, consult your local Authorised Distributor
to check availability of pulleys with Taper Lock bush shaft fixing, and associated
bore size capacity.
BELT LENGTH & CENTRE DISTANCE FORMULAE
To determine belt length (L mm) for a given centre distance
(C mm) using pulleys with small/large effective diameters d/D mm:
L = 2C + (D-d)2 + 1.57 (D+d)
4C
-select the standard belt length nearest to L as calculated.
To determine centre distance for given effective pulley diameters and actual belt length:
C = A + A2 –B
where: A = L – 0.3925 (D + d) and B = (D–d)2

The following recommendations for installing a ribbed belt drive will help ensure correct working conditions
and optimum service life.

SHAFT ALIGNMENT
The maximum axial misalignment allowed is 3 mm per metre centre distance, to a maximum of 15 mm.
Make sure that angular misalignment is kept within 2o. With flat pulleys, acting as idlers for power take-off, do
not exceed 1o.
A laser alignment device is available, which facilitates quick, easy and accurate pulley alignment - consult
your local Authorised Distributor.
TENSIONING THE BELT
Ribbed belts must be tensioned correctly and with great care. Under or over-tensioning can cause functional
problems and lead to premature belt failure. We recommend the elongation method, which is simple and
requires no special equipment, in most cases.
(For narrow belts - less than 40 mm wide - it is possible to use the Fenner Belt Tension Indicator).
1. Fit the belt on the pulleys with no tension,
2. Draw two lines perpendicularly across the belt back approx 80% of the belt span apart (or one metre apart
for very long spans),
3. Increase the distance between the two lines by 0.5 to 0.75% i.e. by 5 to 7.5 mm for an initial spacing of
1000 mm.
4. Run the drive under load for about 10 minutes,
5. Check the tension of the belt (i.e. the spacing between the two lines) and readjust if necessary.

GENERAL
Pulleys should be mounted as close as possible to bearings, to reduce overhung load.
Pulley grooves should be in good condition, clean, and free from sharp edges.
Ensure that drive machinery is securely fastened after belt installation or adjustments.
Guards should be generously sized and well ventilated.
FEN01/14 : DRIVE DESIGN & MAINTENANCE MANUAL 85
The Fenner S.C.I.E.N.C.E. Explained
Did you know that 70% of friction drives are
incorrectly installed?
That figure is quite astounding particularly when you consider how
many applications are dependant on the efficiency and reliability
of friction belt drives.
But don't panic, with a just a few simple steps and the assistance of your
Local Authorised Fenner Distributor, we can ensure that your belt drives (and
chain drives) achieve their optimum efficiency, full operating life and provide
reliable performance.
With Fenner it's all about the S.C.I.E.N.C.E. - Select Correctly, Install
Effectively, Never Compromise Efficiency, if you adhere to these
simple rules you can be confident that your drive selection will perform.
Select Correctly
A correctly selected drive for your application will ensure the drive uses the
fewest number of belts or the absolute minimum of belt width, which in turn.
Reduces loading on the machines bearings increasing the life cycle of the
machine, reducing downtime and the risk of mechanical failure
Reduces the noise levels keeping noise pollution to a minimum at high
speeds
Reduces the amount of raw materials and resources used cutting down
on waste an subsequent pollution
Install Effectively
Correct installation - once you have carefully selected your belt drive
components - is paramount to the longevity and efficiency of your belt drive, by
following the correct installation procedures to the letter and by using the right
tools for the job, such as the Fenner laser alignment and tensioning devices,
we can;
Reduce the vibration to which the machine bearings are subjected,
prolonging machine life, minimising downtime and reducing the risk of
severe damage to the driven machine
Ensure the drive operates and delivers its maximum rated power at its
premium efficiency, reducing both waste and pollution
Supply a drive which gives the maximum drive life available on the
market using the minimum of resource to maintain
Never Compromise Efficiency
By including belt drives as an integral part of a planned maintenance schedule
you can:
Ensure the process up-time is at an absolute maximum giving the ultimate
production output maximising operational efficiency
Prolong the life of the drive and negate the need to waste costly
resources on breakdowns and drive problems
Extend drive, machine and bearing life to the maximum, using less raw
materials and guarantee sustainability.
Remember your drive stands or falls by the accuracy of its installation,
so take the time to get this right and you will reap the rewards. Use
the S.C.I.E.N.C.E
Pulley Groove Gauge
When installing new belts, the condition of the pulleys is often
overlooked. 50% of new belts are fitted to worn pulleys, which
can waste up to 10% of your energy input. The Fenner groove
gauge can quickly help you assess the health of your pulleys.
Request your free pulley
groove gauge from your
Authorised Distribitor.
Belt Tension Indicator
The Fenner Belt Tension Indicator is a simple tool that helps
ensure accurate belt tension - a correctly tensioned drive avoids
belt slippage which can reduce overall drive efficiency.
Belt Efficiency Kit
Get the most from your
wedge belt drives with the
Fenner Belt Efficiency Kit.
The kit contains all the tools
necessary to help achieve
optimum performance: Belt
Tension Indicator, Pulley
Groove Gauge and a simple
guide to efficient wedge belt
efficiency.
Fenner Drive Alignment Laser
The Fenner Drive Alignment Laser is the perfect tool for pulley
and sprocket alignment. Applied magnetically in just a few
seconds, the laser line projects onto targets allowing rapid
adjustment for perfect alignment.
