Exlar’s Tritex Series actuators combine three technologies to deliver a simple and low-cost alternative for fluid power actuators and costly servo systems. Tritex electric actuators combine a brushless motor, servo amplifier and position controller in a single industrial grade enclosure. This eliminates both the external servo amplifier and the cables associated with a typical servo system.

Tritex linear actuators employ Exlar’s patented, inverted roller screw mechanism for converting the rotational motion generated within the actuator to highly robust and long-life linear motion.

Tritex software allows you to create a sequence which causes the the actuator, when commanded, to move forward while pressing an object into position. You can establish a pre-programmed force which triggers an event such as stopping or retracting to another position or it can maintain that force level until commanded otherwise. The sequence is ideal for assembly, test, fastening and pressing applications.

The GSX Series linear actuators offer a complete linear actuator solution, in the most compact package, for nearly any application or environment. The GSX Series includes Exlar’s high capacity inverted roller screw technology, offering 15 times the life of similarly sized ball screws. 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.

Selection of the proper feedback configuration allows GSM Series actuators to be powered by nearly every brand of brushless motor amplifier on the market. 

The GSM Series provides an excellent replacement for ball screw actuators and offers 5 times the travel life of a similarly sized ball screw. This design incorporates Exlar’s patented roller screw technology with an integral brushless servo motor for medium to high performance motion control applications. The GSM design provides a smaller package with higher speed and load capacity and longer life than ball screws and other traditional rotary to linear conversion mechanisms.

Selection of the proper feedback configuration allows GSM Series actuators to be powered by nearly every brand of brushless motor amplifier on the market. 

Exlar I Series Actuators present a new range of alternatives for linear motion solutions. The I Series actuators offer all of the benefits of Exlar's planetary roller screw technology, along with extreme flexibility in actuator mounting style, and the type of motor used to drive the actuator.

Exlar's roller screw technology has been the integral component in creating reliable, long lasting electromechanical actuators. For the last 15 years, Exlar's inverted roller screw actuators have provided a long-life, all-electric replacement for hydraulic cylinders in thousands of applications.


I Series Features:

• Flexible mounting options
• Adapts to various types of motors
• Optional inline planetary gear reducer for high force output from lower motor torques

 

Exlar FT Series force tubes use a roller screw mounted inside a telescoping tube mechanism. The follower is attached to the moveable force tube, which then extends and retracts as the screw rotates. The FT Series is designed to be compatible with a wide variety of standard motors. Motor mounting and gearing configurations are available to meet nearly any application's requirements. The standard product offering includes three frame sizes with strokes from 12 inches to eight feet. The continuous duty thrust load rating is 2,000 to 20,000 lbf with a peak load rating up to 40,000 lbf.

The EL Series linear actuators offer users all of the advantages of Exlar’s patented inverted roller screw actuator designs in a Class I, div 1, Groups B, C or D explosion-proof package. These electro-mechanical systems provide process engineers a clean, fast, simple and cost effective replacement for hydraulic actuation and a longer life alternative to pneumatic actuation. The roller screw technology manufactured by Exlar outperforms rival ball screws by 15 times in travel life and can carry higher loads.

The EL Series actuator is compatible with nearly any manufacturers’ resolver-based amplifier.

Available in diameters from 3.5 to 150mm, Exlar PRS Series roller screws provide solutions to a wide range of applications - from the most compact and precise to the largest and extremely high load requirements.

Exlar’s Tritex Series actuators combine three technologies to deliver a simple and low-cost alternative for fluid power actuators and costly servo systems. Tritex electric actuators combine a brushless motor, servo amplifier and position controller in a single industrial grade enclosure. This eliminates both the external servo amplifier and the cables associated with a typical servo system.

Tritex rotary motors and gearmotors provide higher response and precise control of a rotatable shaft similar to that found in any electric motor. The difference is that with Tritex you can program (via your PC) the rotational speed and position of the output shaft in response to external commands. For example, the motor can be commanded to rotate at a controlled velocity and precisely stop at a pre-programmed position upon receiving a command to do so. You can also program the unit to run at a preset velocity until a switch input is received or a pre-programmed torque level is produced (against a load). Alternatively, the rotary Tritex can be set up to follow an analog signal, either voltage or current, representing torque, velocity, or position.

SLM Series Brushless Motors offer a very compact size/high torque ratio and provide outstanding performance when compared to traditional motion control companies' products. Three frame sizes are available offering continuous torques to 237 lbf-in and speeds to 5000 rpm.

SLG Series Brushless Gearmotors
offer you one of the highest power densities available in motion control. Currently the SLG gearmotors are available in three frame sizes, 60, 90 and 115 mm frames with 1, 2 or 3 stack lengths. Single and double reductions are available in 4:1, 5:1, 10:1, 16:1, 25:1, 40:1, 50:1, and 100:1. Their unique design is especially valued in applications where weight or space is at a premium. SLG gearmotors are UL Recognized.

ER Series Explosion-Proof motors are rated for Class 1, div 1, Groups B, C and D. The compact gearmotor comprises a brushless permanent magnet motor optimized for use with an integral planetary gear set. Through the uniform load sharing of several gears acting in concert, planetary gearheads provide a very compact, reliable solution providing high torque, low backlash and low maintenance.

The ER Series motor can be matched with our digital control, the SV Series, to provide a servo system suitable for hazardous duty. Alternatively, these motors and gearmotors are compatible with nearly any manufacturers' amplifier. 

The SV Series Positioners were designed specifically for use with Exlar rotary and linear actuators to control valves and dampers in process control applications. The all-electric design eliminates the complexity of applying electro-hydraulic interface pilot valves or electric-pneumatic positioners, and provides two-way communication between your system and the actuator.

The fully digital SV Series Positioners operate from standard process control inputs allowing for simple retrofits of hydraulic or pneumatic actuated valve applications or dampers. SV Series Positioners used with Exlar's high performance linear and rotary actuators can also replace fluid power and low performance electric actuators, eliminating problems associated with actuator failures.
