GSX Series – The Highest
Performance, Longest Life and
Most Compact Linear Actuators!
GSX Series linear actuators combine
the advantages of Exlar’s roller screw
technology and T-LAM™ technology
to create the next generation of linear
actuators. Exlar uses a specially
designed roller screw mechanism for
converting electric motor power into
linear motion within the actuator.
Planetary rollers assembled around
the actuator’s extending rod follow
threads which are precisely machined
on the inside surface of the actuator’s
hollow armature. Linear motion is
produced in precise synchronization
with the armature rotation. Because
this roller screw mechanism has an
inherently larger cumulative contact
surface, these actuators have a much
longer working life, and can handle
heavier loads at higher speeds than
is possible from a similarly sized unit
built around a ball screw system.
Exlar’s T-LAM segmented lamination
stator technology delivers higher
continuous motor torque than is
available in traditionally wound
motors. T-LAM technology consists
of stator segments, each containing
individual phase wiring for maximum
motor performance. The improved
efficiencies of the GSX Series
are a result of the limited
heat generation qualities
inherent in the segmented
stator design as seen
above. The elimination of
end turns in the stator, and
use of thermally conductive potting
removes the parts most susceptible
to failure in a traditional stator. Other
design advantages include:
• Neodymium-iron-boron magnets
provide high flux density and maxi-
mum motor torque.
• Thermally conductive potting of the
entire stator provides increased
heat dissipation and provides pro-
tection from contamination in oil-
cooled units.
• Each stator segment contains indi-
vidual phase wiring. External wind-
ing of individual segments provides
maximum slot fill for maximum
motor performance.
• Motors with T-LAM technology
have Class 180 H insulation sys-
tems compliant with UL require-
ments.
• UL recognized component.
• Motors with T-LAM technology are
CE compliant

Actuator & Motor,
All in one Compact Unit.
With other actuator technolo-
gies, customers are usually respon-
sible for engineering the completed
linear motion system. This usually
includes purchasing the motor, gear
reducer, timing belt, mounting hard-
ware, flexible couplings, etc. sepa-
rately. Then they all must be assem-
bled to perform properly in a given
application.

GSX Series Linear Actuators
GSX Series actuators eliminate all
this systems engineering. These
units are single, fully integrated com-
ponent packages – much smaller
than traditional rotary-to-linear con-
version mechanisms.
Designed for Closed Loop Servo
Systems
Their brushless servo design means
GSX Series units can be used in
advanced closed-loop servo systems
when velocity and positioning is
required. Position feedback can be
delivered in a number of different
forms. These include
resolvers, encoders or
internally mounted linear
position feedback sen-
sors.
Sealed for Long Life
with Minimum
Maintenance
GSX Series actuators
have strong
advantages
whenever out-
side contami-
nants are an issue. In most rotary-to-
linear devices, critical mechanisms are
exposed to the environment. Thus,
they must be frequently inspected,
cleaned and lubricated.
In contrast, the converting components
in all Exlar GSX units are mounted
within the sealed motor housing. With
a simple bushing and seal arrangement
on the smooth extending rod, abrasive
particles or other contaminants are
prevented from reaching the actuator’s
critical mechanisms. This assures
trouble-free operation even in the most
harsh environments.
Lubrication requirements are minimal.
GSX actuators can be lubricated with
either grease or recirculated oil.
Grease lubricated units will run up to
10,000 hours without re-greasing.
Recirculated oil systems eliminate this
type of maintenance altogether. A GSX
Series actuator with a properly operat-
ing recirculating oil system will operate
indefinitely without any other lubrica-
tion requirements.

In clean room
applications like those
common to semiconductor
manufacturing, the compact
design of our GSX Series saves
critical space.
Because they
cycle quickly and
can be synchronized to line speeds,
Exlar actuators produce dramatic
improvements in web control applica-
tions.
Repeatable force, reliable posi-
tioning accuracy, and flexible con-
trol make GSX actuators a

GSX Series Lifetime Curves
The L10 expected life of a roller screw linear actuator
is expressed as the linear travel distance that 90% of
properly maintained roller screws manufactured are
expected to meet or exceed. This is not a guarantee
and these charts should be used for estimation
purposes only.
The underlying formula that defines this value is:
Travel life in millions of inches, where:
C= Dynamic load rating (lbf)
F= Cubic mean applied load (lbf)
S= Roller screws lead (inches)
L10 =
(
C
)
3x S≡
F
All curves represent properly lubricated and maintained actuators.

GSX50 & GSX60 Performance Specifications
Specifications subject to change without notice.
Force Rating: The linear force produced by
the actuator at continuous motor torque.
Max Velocity: The linear velocity that the
actuator will achieve at rated motor rpm.
Continuous Motor Torque: Torque produced
by the motor at rated continuous current.
Maximum Static Load: The mechanical load limit
of the actuator if re-circulated oil or other cooling
method is used to allow higher than rated torque
from the motor.
Armature Inertia: The rotary inertia of the arma-
ture of the GSX Series actuators. For calculation
purposes, this value includes the screw inertia in a
GSX actuator.
Dynamic Load Rating: A design constant used
in calculating the estimated travel life of the
roller screw. The cubic mean load is the load
at which the device will perform one million
revolutions.
* GSX offers 1, 2, or 3 stack stators providing 3
torque force levels.

GSX Series Cable and
Connector Selection
This section provides you with cable
part numbers for operation of your
GSX Series actuators with both
Exlar’s and other manufacturers’
servo drives.
The "O" connector option on the
GSX Series of actuators provides
for an actuator with Exlar’s standard
MS style connectors, compatible
with Exlar’s standard cables.
The "M" connector option on the
GSX series of actuators provides
for an actuator configured with
connectors that allow the end user
to purchase the feedback cable or
power and feedback cables from
the manufacturer of their servo
amplifier, thus eliminating the
headaches and confusion that can
arise from power and feedback
wiring.
Depending on actuator size, volt-
age, and cable availability from the
amplifier manufacturer, some
cables must be obtained from Exlar.
For amplifier manufacturers who
use standard style military connec-
tors, with molded and shielded
cables, the feedback cable can be
purchased from the amplifier man-
ufacturer, and the power cable pur-
chased from Exlar. The Exlar power
cables with the PCx-MC-xxx model
numbers are molded and shielded
and provide a good match with the
cables provided by the amplifier
manufacturer.
For some amplifier manufacturers
who utilize a different style of con-
nector, when the "M" option is avail-
able from Exlar, both the connectors
will be configured to allow the feed-
back and power cables to be pur-
chased from the amplifier manufac-
turer. Consult Exlar for details on
all connector configurations.

As shown in the schematic to the left, a check valve
or other method of pressure regulation should be
used to maintain an internal actuator oil pressure of
5 psi.
Filtering of 25 microns or better should be used.
Simple radiators or heat exchangers can be
used to maintain oil temperature.
Locate oil system
as close to
actuator as
possible. Use
as large as
possible oil line
to minimize any
possibility of

High Power/Minimal
Maintenance Operation
Guidelines
Exlar GSX series actuators can be
lubricated with either grease or oil.
All are shipped from the factory
fully greased and are capable of
functioning for many thousands of
hours between re-greasings.
Typically, greased lubrication is
preferred for lower speed or inter-
mittent duty applications. In these
situations, you simply mount the
actuator, connect the servo amplifi-
er, and run.
However, many GSX Series actua-
tors are deployed into applications
Simple Oil System Schematic
involving high speed, high force, or
both. To provide the cooling
required when operating at these
high power levels and/or to elimi-
nate periodic re-greasing, all GSX
units have another built-in feature.
They are designed with an internal
circulation path and the portings
necessary for customers to convert
from grease by connecting a recir-
culation oil system. This feature
makes GSX units the only all-elec-
tric actuators on the market capable
of true continuous-duty perform-
ance in moderate and high power
applications when heat is an issue.
The conversion to externally sup-
plied oil is simple. Identify which
port will be lowest when the actua-
tor is mounted. That will become
the oil supply side. (For optimum
cooling it is important that GSX
actuators are mounted so the high-
side port is at least above the unit’s
centerline, preferably in the top
quarter region. This assures that
the stator windings receive the oil’s
cooling benefits.) Just connect
your oil lines and you’re done.
Residual grease will be flushed out
and filtered during initial operation.
A typical oil cooling system is
shown below. Whenever applica-
tion requirements are such that the
RMS current requirement exceeds
the continuous current rating of the
GSX motor, oil cooling should be
used to keep case temperatures
below their 85˚C maximum specifi-
cation. For very high speed appli-
cations, consult Exlar for oil routing
recommendations.

Exlar recommends the use of petroleum based gear oils with EP additive. An ISO 100 grade is suitable for most
applications. Examples of this type of oil are: Mobil Mobilgear, Exxon Spartan EP, Shell Omala and Texaco Meropa.
Oils meeting the FDA’s food grade specifications are also available such as Mobil DTE FM 32.

Oil Cooling and Lubrication
Oil lubrication will extend the life of
the actuator and improve its effi-
ciency. More importantly, oil is
required in high power applications

Exlar’s application engineers or local representative for details.
for cooling. In applications where
the RMS current exceeds IG (see
electrical specs on pages 13-17),
oil lubrication is required in order
to maintain the case temperature
below its maximum of 85°C1.
When such oil lubrication is
required, you can determine oil
flow rates and case temperatures
from this information:
Actuator Load Constants: KL = ( )
KL GSX20 = 40
KL GSX30 = 70
KL GSX40 = 95
KL GSX50 = 125
KL GSX60 = 260

CASE 1:
A GSX30-238 requires 4 amps of RMS current to perform the required application. The incoming oil tem-
perature is 45°C, and we desire to maintain the actuator at it’s maximum case temperature of 85°C.
FL = (4/3.4)2= 1.38 W = [(1.38 x 70)/(85 – 45)] = 2.415 GAL / HOUR
CASE 2:
A GS45 requires 12 amps of RMS current to perform the required application. The incoming oil tempera-
ture is 45°C, and we desire to maintain the actuator at it’s maximum case temperature of 85°C.
FL = ( 12/8 )2= 2.25 W = [( 2.25*125 ) / (85 – 45)] = 7.0 GAL / HOUR

GSX Series Linear
Actuator Anti-rotation
Option
The unique design of the
GSX Series of linear actua-
tors permits the extending
rod to rotate. This simplifies
actuator setup by allowing
the user to rotate the rod and
thread it in and out of the
actuator for mechanical
attachment or system testing.
However, this feature also
requires that once setup and
testing are completed, the
rod be kept from rotating so
proper linear motion will be
maintained. In most applica-
tions the actuator’s load is
coupled to linear bearings, or
some other support device.
In these cases the load can-
not rotate, and a separate
anti-rotation system is not
needed.
For applications in which the
load is free to rotate, Exlar
offers the anti-rotation sys-
tems shown below. Shorter
GSX units use an anti-rota-
tion arm on one side of the
actuator. Longer strokes
(defined above right) use
rods on both sides.

Anti-rotation Option GSX50
GSX Series Travel Options
PF = Preloaded Follower
This option offers a true zero backlash follower for the GSX Series actuator. The dynamic load rating of zero backlash,
preloaded screws is 63% of the dynamic load rating of the standard non-preloaded screws. The calculated travel life of a
preloaded screw will be 25% of the calculated travel life of the same size and lead of a non-preloaded screw for the same
application. Preloaded follower is not available with absolute internal feedback option.
EB = Electric Brake
This option provides an internal holding brake for the GSX20, 30, 40 & 60 actuators. The brake is spring activated and
electrically released.
RB = Rear Electric Brake
This option provides an internal holding brake for the GSX50 actuator. The brake is spring activated and electrically
released.
ES = Internal End of Travel Switches
This option allows for two internal end of travel switches to be included with the GSX Series actuator. These switches
provide end of travel indication to the controller and are not adjustable. See page 31 for details.
AR = External Anti-rotate Assembly
This option provides a rod and bushing to restrict the actuator rod from rotating when the load is not held by another
method. Shorter actuators have single sided anti-rotation attachments. Longer lengths require attachments on both
sides for proper operation.
XT = Special Travel Option Selections
The XT Option can be used to specify various special travel options on the GSX Series of Linear Actuators. Because this
option can be used to specify many things, it is important that an order including the -XT option spell out in detail, the
exact options being selected by the including of the -XT in the model number.
It is recommended that prior to ordering an actuator including the -XT specifier that a quote be obtained through Exlar’s
special products application engineers for the desired options, and that quote be referenced on, or included with any
order placed.

This option provides an accordion style protective bellows to protect the main actuator rod from damage
due to abrasives or other contaminants in the environment in which the actuator must survive. The stan-
dard material of this bellows is neoprene coated nylon. This standard bellows is rated for envi-
ronmental temperatures of -54 degrees to 121 degrees Celsius. Longer strokes may require
the main rod of the actuator to be extended beyond standard length. Consult Exlar appli-
cations engineers for details.
This option provides an accordion style protective bellows to protect the main
actuator rod from damage due to abrasives or other contaminants in the environ-
ment in which the actuator must survive. The high temperature material of this
bellows is silicone coated fiberglass. This standard bellows is rated for environmen-
tal temperatures of -73 degrees to 288 degrees Celsius. Longer strokes may require the main rod of the
actuator to be extended beyond standard length. Consult Exlar applications engineers for details.
This option provides a main rod manufactured of ball spline shafting, and the front seal and
bushing assembly replaced with a ball spline nut to provide the anti-rotate function with-
out using an external mechanism. Rod diameters are the closest metric equivalents
to standard Exlar rod sizes. This option is NOT sealed in any way. This option is
not suitable for any environment in which contaminants come in contact with the
actuator, and may enter the actuator.
This option provides for a manual drive handwheel on the side of the actuator. The hand-
wheel has a engagement/disengagement lever which allows for disengagement
of the handwheel during operation. This engagement/disengagement lever
is not tied to the operation of the motor and requires that the user guaran-
tee its disengagement before operating the motor. Not available on
GSX20.
L1, L2, L3 = Adjustable External Travel Switches
This option allows up to 3 external switches to be included with the GSX Series Actuator. These switches provide travel
indication to the controller and are adjustable (must purchase anti-rotate for this option). See page 32 for details.
XL =Non-Standard Lubrication
This option provides for indication in the model number that the customer has specified a lubrication other than the stan-
dard provided by Exlar.

GSX Series
Motor Speed Designators
All Exlar T-LAM™ motors and actuators carry a standard motor
speed designator as defined below. This is representative of the
standard base speed of the motor, for the selected bus voltage.
Designator Base Speed Actuator/Motor Series
-50 5000 rpm GSX20
-30 3000 rpm GSX30, GSX40
-24 2400 rpm GSX50, GSX60
01-99 Special Speed, Consult Exlar
If the model number is created and the location for the motor speed
designator is left blank, this is the base speed to which each motor
will be manufactured. The model number can also be created
including this standard speed designator.
Exlar also provides the flexibility to manufacture all of its T-LAM
products with special base speeds to match the customer’s exact
application requirements. This may be a higher than standard
speed motor, or lower base speed than standard which will allow
the customer to get the required torque, at a speed optimized to
their application, and use the minimum amount of current from
their amplifier.
The call out for a special speed is configured in the model number
by using a two digit code from 01-99. These numbers represent the
number, in hundreds, of RPM that will be the base speed for the
particular motor.
For example, an GSX-30-03-01-OSM-AD1-118-30 motor that nor-
mally has a 3000 rpm standard winding, can be changed to a 3300
rpm winding by changing the -30, to a -33. It can be changed to a
5000 rpm winding by changing the -30 to a -50.
Changing this speed designator will change the ratings of the
motor, and these must be obtained from Exlar applications engi-
neers. Also, it is not possible to produce every possible speed
from -01 to -99 for each motor at each voltage so please contact
Exlar applications engineers for confirmation of the speed that is
desired for the application.
Absolute Linear Feedback Options
LT = LVDT (VRVT) including conditioner
This option provides for an actuator containing an internally
mounted LVDT (VRVT) transducer spanning the full stroke of
the actuator. Inquire with Exlar engineering for details and con-
ditioner output preference.
Motor Options
GSX motor options are described with a 3
digit code. The first digit calls out the stack
length, the second the rated bus voltage,
and the third the number of poles of the
motor. Refer to the mechanical/electrical
specifications for motor torque and actuator
rated force.
118 = 1 stack, 115 Vrms, 8 Pole, Class 180 H
138 = 1 stack, 230 Vrms, 8 Pole, Class 180 H
158 = 1 stack, 400 Vrms, 8 Pole, Class 180 H
168 = 1 stack, 460 Vrms, 8 Pole, Class 180 H
218 = 2 stack, 115 Vrms, 8 Pole, Class 180 H
238 = 2 stack, 230 Vrms, 8 Pole, Class 180 H
258 = 2 stack, 400 Vrms, 8 Pole, Class 180 H
268 = 2 stack, 460 Vrms, 8 Pole, Class 180 H
318 = 3 stack, 115 Vrms, 8 Pole, Class 180 H
338 = 3 stack, 230 Vrms, 8 Pole, Class 180 H
358 = 3 stack, 400 Vrms, 8 Pole, Class 180 H
368 = 3 stack, 460 Vrms, 8 Pole, Class 180 H

The external limit switch option for the GSX Series of linear actuators provides the user with 1, 2 or 3 exter-
nally mounted adjustable switches for use as the end of travel limit switches or home position sensors.
The number of switches desired is selected by ordering the L1, L2 or L3 option, in which 1, 2 or 3 switches
will be provided, respectively.
The switches are 9-30 VDC powered, PNP output, with either normally open or normally closed logic opera-
tion depending on the switch configuration ordered. Below is a diagram which logic operation will be pro-
vided for each switch, based on the option ordered.

1. The dynamic load rating of zero backlash, preloaded screws is 63% of the dynamic
load rating of the standard non-preloaded screws. The calculated travel life of a
preloaded screw will be 25% of the calculated travel life of the same size and lead
of a non-preloaded screw. Preloaded follower is not available with absolute internal
feedback option.
2. Stator voltage and pole options allow for catalog rated performance at varying
amplifier bus voltages and pole configuration requirements.
3. Linear feedback is not available in the GSX20.
4. Emerson EN and Epsilon Series, AB Ultra Series, Kollmorgen ServoStar and other
amps require motor data files for operation with GSX Series actuators. These files
can be downloaded from our website
at www.exlar.com. Contact Exlar for details.
5. The internal limit switch or brake options require a third cable. Internal limit
switches and brake together are not available.
6. These housing options would typically be accompanied by the choice of the electro-
less nickel connectors if a connectorized unit were selected. This choice may also
indicate the need for special material main rods or flanges.
7. Available with AB1, AB4/5, AB7, EM2, KM1, KM3, KM4, KM5, KM6, IN1, IN2, IN4,
LZ1, LZ2, PC3, PS3, YS2 and YS3 feedback. This option allows the customer to
use the standard cables supplied by their amplifier manufacturers.
8. Use of the A-B 1394 requires assistance from Allen-Bradley to configure the axis
for a custom motor.
