GSA Actuators
The GSA linear slide actuator is ideal for medium- to high-thrust applications.
GSA Linear Slide Actuators combine an electric rod actuator with an integrated guide body, for compact applications where external guides can’t be used. The GSA offers high performance, dependability and mounting flexibility for high value applications.
- 4 Body Sizes
- Forces up to 4,160 lbf (18.5 kN)
- Stroke lengths up to 36 in (914 mm)
- Acme, Ball, and Roller Screw options
- Choice of linear ball or composite guide bearings
- Oversized guide rod options for high load situations
