Actuation Division
GSM Series electric linear actuators are a superior and cost effective alternative to traditional electric, hydraulic and ball screw systems. The compact design is the culmination of advanced roller screw technology and an integral brushless servo motor. This robust electric linear actuator is ideal for a variety of medium- to high-performance applications. With GSM actuators, everything from food and beverage packaging, to multi-axis turning centers, to aircraft assembly can be done cleaner, faster, and more accurately and efficiently.
The powerful T-LAM motor design generates 35% more torque from the same size package. These innovative actuators can be driven by almost any brand of brushless servo motor amplifier. This flexible and programmable motion control system has the capability to provide position feedback from resolvers, encoders or internally mounted sensors. It is a power dense solution that accommodates greater loads, extends travel life and minimizes maintenance. GSM by Exlar® is the new standard of excellence in standard capacity all-electric actuators.
AA = GSM Actuator Size (nominal) BB = Stroke Length CC = Screw Lead D = Connections E = Mounting F = Rod End Thread / Rod Material
Your choice of drive will dictate the appropriate feedback device for your situation. Options for feedback type include an array of absolute, analog and incremental encoders, as well as custom feedback alternatives.
Motor Stator options are described with a 3-digit code. The first digit calls out the stack length, the second digit designates the rated bus voltage, and the third digit identifies the number of poles. Please refer to the mechanical/electrical specifications for motor torque and actuator rated force.
Motor Stators (all 8 Pole and Class 180H)
1A8 = 1 stack, 24 VDC *
2A8 = 2 stack, 24 VDC *
1B8 = 1 stack, 48 VDC *
2B8 = 2 stack, 48 VDC *
1C8 = 1 stack, 120 VDC *
2C8 = 2 stack, 120 VDC *
118 = 1 stack, 115 VRMS
218 = 2 stack, 115 VRMS
138 = 1 stack, 230 VRMS
238 = 2 stack, 230 VRMS
158 = 1 stack, 400 VRMS
258 = 2 stack, 400 VRMS
168 = 1 stack, 460 VRMS
268 = 2 stack, 460 VRMS
* Low voltage stators may be limited to less than catalog rated torque and/or speed. Please contact your local sales representative when ordering this option.
All Exlar T-LAM™ motors and actuators have a standard motor speed designator (described below). The designator represents the standard base speed of the motor for the selected bus voltage.
Note: It is not possible to produce every possible speed for each motor at each voltage. *
This assembly restricts the actuator output rod from rotating when the load is not held by another method. Shorter actuators have a single anti-rotation mechanism; longer lengths have a mechanism on both sides.
External travel switches indicate travel to the controller and are adjustable for either the home or end position.
This is a rear, internal holding brake. The rear brake is spring activated and electrically released.
A ball spline shafting main rod with a ball spline nut that replaces the standard front seal and bushing assembly. This rod restricts rotation without the need for an external mechanism. The rod diameter will be the closest metric equivalent to our standard rod sizes. Since this option is NOT sealed, it is not suitable for environments in which contaminants may enter the actuator.
Note: Adding this option affects the overall length and mounting dimensions.
AA = Actuator Frame Size (nominal) BB = Stroke Length CC = Screw Lead (position change per motor revolution) D = Connections E = Mounting F = Rod End Thread / Rod Material
GGG = Feedback Type Your choice of drive will dictate the appropriate feedback device for your situation. Options for feedback type include an array of absolute, analog and incremental encoders, as well as custom feedback alternatives.
H = Motor Stacks I = Voltage Rating J = Motor Poles
Construction of equipment that, under normal operating conditions, is not capable, due to arcing or thermal effects, of igniting the flammable gas-, vapor-, or dust-air mixture.
The XL option in the model number specifies some form of lubrication other than the standard provided by Exlar®, which is Mobilith SHC220. Special lubricants include other greases, such as JAX FG-2 food grade or Mobilgrease 28. Another non-standard option is oil cooling.*
Special Motor Options should be listed as XM and must be approved by Exlar.*
Please note that specialized rod end attachments must be ordered separately from the actuator.
CP = Clevis Pin RC = Rear Clevis Pin RE = Rod Eye SRM = Spherical Rod Eye
* Some options are not available with every configuration. For options or specials not listed above or for extended temperature operation, please consult Exlar Applications Engineering.
