1.0 INTRODUCTION

1.1 GENERAL PRODUCT DESCRIPTION

GTX Series actuators feature a robust planetary roller screw 
mechanism integrated into the rotor of a brushless servomotor. 
This unique design combines the high speed and high load 
capacity of the roller screw with the high torque-to-volume ratio 
of the brushless servomotor.

Completing the actuator design is the choice of feedback 
devices. The most common types of feedback devices are 
resolvers, incremental encoders, and absolute encoders. 

Selecting the proper feedback configuration allows GTX Series 
actuators to be powered by brushless motor amplifiers readily 

available from most leading motor manufacturers.

GTX Series actuators offer a true all-electric replacement solu

-

tion for cumbersome, high-maintenance hydraulic systems. 
Electronic servo control also provides simpler setup and more 

precise control than hydraulic systems. This flexibility makes 

GTX Series actuators an excellent motion control solution for 
today’s highest performance single- and multi-axis applications. 
From food and beverage packaging to multi-axis turning centers 
to aircraft assembly, GTX Series actuators deliver outstanding 
performance and durability.

GTX Series actuators feature an Ingress Protection Rating  
of IP65S.
