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. 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. (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). (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. (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). TABLE 2 (f) Pulley Pitch Diameters 1000 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. 800 (g) Belt Length, Centre Distance and Correction Factor 400 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. 300 DESIGN POWER kW 600 500 QXPC only X Q PC S 200 QXPB only PB S & U PB B SP X Q 100 A XP A SP Q 60 50 PZ QX Z SP 40 Refer to the power rating tables (pages 52 to 61) for the section and type of wedge belt chosen.

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. 72 friction belt drives Section : 3 PowerTwist PLUS® Belting 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.

FEN01/14 : Drive Design & Maintenance Manual 75 Section : 3 FRICTION BELT drives Fenner Wedge and Vee-Belt Tensioning Instructions "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. BELT TENSION INDICATOR APPLIES SETTING FORCE AT MID CENTRE DISTANCE The setting forces below are designed to cover a wide range of drives. A precise setting force for individual applications can be calculated. Please consult your local Authorised Distributor or use the 'Fenner Select' design software at www.fptgroup.com 16 pe mm ce r 1 m defle ntr et ct e d re o ion ista f nc e 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 entrapment between belts and pulleys) Setting Forces Ultra PLUS 150 Belt Section USPB 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.

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. friction belt drives Section : 3 Installation and Operation of Wedge and Vee-Belt Drives 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. 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. 1 Angular misalignment 2 Composite misalignment The modern wedge belt drive is a highly efficient power transmission medium, but optimum performance will not be achieved without correct tension and alignment. 3 Axial misalignment Installation 4 Correct installation -both shafts and pulleys are parallel and in alignment. 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 FEN01/14 : Drive Design & Maintenance Manual Belt Pitch Length (mm) 410 to 530 530 to 840 850 to 1160 1170 to 1500 1510 to 1830 1840 to 2170 2180 to 2830 2840 to 3500 3520 to 4160 4170 to 5140 5220 to 6150 6180 to 7500 7600 to 8500 8880 to 10170 10600 to 12500 INSTALLATION AND TAKE-UP ALLOWANCE Installation Allowances SPZ SPA SPB SPC Z A B C 8V D 20 25 Taper Lock All Fenner V and wedge belt pulleys use Taper Lock shaft fixing.

How to Measure 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. Correct way to measure: PowerTwist Plus – end of tab to first empty holes (right to left, above) 2. Assembly - PowerTwist PLUS 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. 3. Installation 4. Retensioning Make PowerTwist Plus belts to the correct pitch length and then install them as you would an endless belt. 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. 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.

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. *NOTE: 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 lower value indicates under-tensioning. A new drive should be tensioned to the higher value to allow for the normal drop in tension during the running-in period. After the drive has been running for 30 minutes, the tension should be checked and re-adjusted to the higher value, if necessary. 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. 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. 78 Pull end of link over tab. Rotate belt end with tab at 90º to line of belt.

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. 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. SPEED INCREASE RATIO Use the formulae below to establish which standard belt length (listed page 79) gives closest to the required drive centre distance. friction belt drives Section : 3 PolyDrive PLUS Belt Selection TABLE 2 TABLE 3 BELT LENGTH CORRECTION FACTOR Design Power – kW Pitch Length 300 250 200 150 m 0m 6M x1 40 M 100 70 60 50 40 30 m 0m 6L x1 L 18 20 10 mx m 160 7 6 5 4 16 J 8L mx m 75 3 J mx 2 m 71 8J 1.0 0.7 0.5 200 300 400 500 600 800 1000 1500 2000 2500 3000 4000 5000 6000 Rev/min of FASTER SHAFT mm ins PJ Cross Section PL PM 610 660 711 762 813 864 914 965 1016 1092 1168 1270 1397 1550 1562 1664 1752 1765 1842 1956 1981 2134 2286 2324 2388 2515 2693 2921 3124 3327 3696 3734 4089 4191 4470 4648 5029 5385 5410 6121 6883 7646 8408 9169 9931 24.0 26.0 28.0 30.0 32.0 34.0 36.0 38.0 40.0 43.0 46.0 50.0 55.0 61.0 61.5 65.0 69.0 69.5 72.5 77.0 78.0 84.0 90.0 91.5 94.0 99.0 106.0 115.0 123.0 131.0 145.5 147.0 161.0 165.0 176.0 183.0 198.0 212.0 213.0 241.0 271.0 301.0 331.0 361.0 391.0 0.89 0.90 0.92 0.93 0.95 0.97 0.98 0.99 1.00 1.01 1.02 1.05 1.07 1.09 – – 1.12 – – 1.15 – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – 0.89 0.91 – 0.93 0.94 – 0.96 0.97 – 0.98 1.01 – 1.02 – 1.04 1.05 1.07 1.08 1.10 1.12 – 1.14 1.14 1.16 – 1.19 1.20 – – – – – – – – – – – – – – – – – – – – – – – – – – – – – 0.88 – 0.89 0.90 0.91 0.93 0.94 0.96 – 0.98 1.00 1.00 1.02 1.03 1.05 – 1.06 1.09 1.12 1.14 1.16 1.18 1.20 TABLE 4 ARC OF CONTACT CORRECTION FACTORS D–d C Arc of contact (degrees) Correction Factor D–d C Arc of contact (degrees) Factor 0.00 0.05 0.10 0.15 0.20 0.25 0.30 0.35 0.40 0.45 180 177 174 171 169 166 163 160 157 154 1.00 0.99 0.99 0.98 0.97 0.97 0.96 0.95 0.94 0.93 0.50 0.55 0.60 0.65 0.70 0.75 0.80 0.85 0.90 0.95 151 148 145 142 139 136 133 130 127 123 0.93 0.92 0.91 0.90 0.89 0.88 0.87 0.86 0.85 0.83 TABLE 5 Speed of motor shaft rev/min 720 960 1440 2880 0.55 50 45 40 40 0.75 50 50 45 45 1.1 67 56 50 50 1.5 70 63 63 56 FEN01/14 : Drive Design & Maintenance Manual 2.2 75 70 67 63 3.0 85 75 71 67 4.0 95 85 80 71 Recommended Minimum Motor Pulley Diameter (mm) Design Power (kW) 5.5 7.5 11.0 15.0 18.5 22.0 30.0 37.0 106 118 132 150 160 165 180 190 90 100 118 125 132 150 165 180 85 90 100 118 125 132 150 165 75 80 90 95 100 118 125 132 45.0 200 190 170 150 55.0 224 212 190 160 75.0 250 224 200 165 93.0 280 250 224 180 112 315 280 250 190 130 315 315 280 200 150 315 315 280 224 81 Section : 3 FRICTION BELT drives PolyDrive PLUS Power Ratings TABLE 6 SPEED RATIO CHART Drive (motor) pulley eff. dia. mm 71 Driven pulley eff. dia mm 75 80 85 90 95 100 106 112 118 125 132 140 150 160 170 180 71 1.00 75 1.05 1.00 80 1.12 1.06 1.00 85 1.19 1.13 1.06 1.00 90 1.26 1.19 1.12 1.06 1.00 95 1.32 1.25 1.18 1.11 1.05 1.00 100 1.39 1.32 1.24 1.17 1.11 1.05 1.00 106 1.47 1.39 1.31 1.24 1.17 1.11 1.06 1.00 112 1.55 1.47 1.38 1.31 1.24 1.17 1.12 1.05 1.00 118 1.63 1.55 1.46 1.37 1.30 1.23 1.17 1.11 1.05 1.00 125 1.72 1.64 1.54 1.45 1.37 1.30 1.24 1.17 1.11 1.06 1.00 132 1.82 1.73 1.62 1.53 1.45 1.38 1.31 1.24 1.17 1.12 1.05 1.00 140 1.93 1.83 1.72 1.62 1.53 1.46 1.39 1.31 1.24 1.18 1.12 1.06 1.00 150 2.06 1.96 1.84 1.73 1.64 1.56 1.48 1.40 1.33 1.26 1.19 1.13 1.07 1.00 160 2.19 2.08 1.96 1.85 1.75 1.66 1.58 1.49 1.42 1.35 1.27 1.21 1.14 1.07 1.00 170 2.33 2.21 2.08 1.96 1.86 1.76 1.68 1.58 1.50 1.43 1.35 1.28 1.21 1.13 1.06 1.00 180 2.46 2.34 2.20 2.07 1.96 1.86 1.77 1.68 1.59 1.51 1.43 1.35 1.28 1.20 1.12 1.06 1.00 190 2.60 2.46 2.32 2.19 2.07 1.96 1.87 1.77 1.68 1.59 1.51 1.43 1.35 1.26 1.18 1.12 1.05 200 2.73 2.59 2.44 2.30 2.18 2.07 1.97 1.86 1.76 1.67 1.58 1.50 1.42 1.33 1.24 1.17 1.11 212 2.89 2.75 2.58 2.44 2.30 2.19 2.08 1.97 1.87 1.77 1.68 1.59 1.50 1.40 1.32 1.24 1.17 224 3.05 2.90 2.72 2.57 2.43 2.31 2.20 2.08 1.97 1.87 1.77 1.68 1.59 1.48 1.39 1.31 1.24 236 3.21 3.05 2.87 2.71 2.56 2.43 2.31 2.19 2.07 1.97 1.86 1.77 1.67 1.56 1.46 1.38 1.31 250 3.40 3.23 3.04 2.86 2.71 2.57 2.45 2.32 2.19 2.09 1.97 1.87 1.77 1.65 1.55 1.46 1.38 280 3.81 3.61 3.40 3.20 3.03 2.88 2.74 2.59 2.45 2.33 2.21 2.09 1.98 1.85 1.73 1.63 1.54 315 4.28 4.06 3.81 3.60 3.41 3.23 3.08 2.91 2.76 2.62 2.48 2.35 2.22 2.07 1.95 1.84 1.74 355 4.81 4.57 4.29 4.05 3.83 3.64 3.46 3.27 3.10 2.95 2.79 2.65 2.50 2.34 2.19 2.07 1.95 400 5.42 5.14 4.83 4.56 4.32 4.10 3.90 3.68 3.49 3.32 3.14 2.98 2.81 2.63 2.47 2.33 2.20 450 6.09 5.78 5.43 5.12 4.85 4.60 4.38 4.14 3.93 3.73 3.53 3.35 3.16 2.95 2.77 2.61 2.47 500 6.26 6.41 6.03 5.69 5.39 5.11 4.86 4.60 4.36 4.14 3.92 3.72 3.51 3.28 3.08 2.90 2.74 630 8.50 8.07 7.59 7.16 6.78 6.43 6.12 5.79 5.48 5.21 4.93 4.68 4.41 4.13 3.87 3.65 3.45 800 10.79 10.24 9.62 9.08 8.59 8.16 7.76 7.34 6.96 6.61 6.25 5.93 5.60 5.23 4.91 4.63 4.38 The above chart gives approximate speed ratios between pulleys of the shown effective diameters.

With flat pulleys, acting as idlers for power take-off, do o not exceed 1 . 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. 1000 mm (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, 1007.5 mm 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. C after take -up GENERAL Calculated C Pulleys should be mounted as close as possible to bearings, to reduce overhung load. C for fitting 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.

Explained Did you know that 70% of friction drives are incorrectly installed? 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. Product Ref: 230A0000 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. 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. 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. n Reduces loading on the machines bearings increasing the life cycle of the machine, reducing downtime and the risk of mechanical failure n Reduces the noise levels keeping noise pollution to a minimum at high speeds n 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; n 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 n Ensure the drive operates and delivers its maximum rated power at its premium efficiency, reducing both waste and pollution n Supply a drive which gives the maximum drive life available on the market using the minimum of resource to maintain Product Ref: 230L0000 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. Never Compromise Efficiency By including belt drives as an integral part of a planned maintenance schedule you can: n Ensure the process up-time is at an absolute maximum giving the ultimate production output maximising operational efficiency n Prolong the life of the drive and negate the need to waste costly resources on breakdowns and drive problems n 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 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.
