Page 3: Introduction
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. -

Page 5: System Configuration
2.0 SYSTEM CONFIGURATION 2.1 GTX SERIES ACTUATOR GTX Series actuators provide a robust solution for long-life, continuous-duty applications even when environmental contaminants are an issue. In most rotary-to-linear devices, critical mechanisms are exposed to the environment and must be frequently inspected, cleaned and lubricated. In contrast, GTX Series actuators are designed with all converting components mounted within sealed motor housings. -

Page 11: Lubrication
3.3 LUBRICATION GTX Series actuators are shipped from the factory fully greased and ready for installation. Exlar uses Mobil SHC 220, a high- performance grease that performs well under extreme pressure. The unique physical properties of the synthetic-based oil provide outstanding protection against wear, rust, corrosion and high- or low-temperature degradation. Mobil SHC allows for very low starting and running torque values. -
