RSA & GSA Electric Rod-Style Actuator What ARE the RSA & the GSA? Flexibility defines the RSA and the GSA. Need a basic electric screw-driven rod-style actuator? Choose the RSA. Need a rod style actuator that provides guidance and support for the load? Choose the GSA. Every actuator is built-to-order in the stroke length you specify, shipped in 5 days or less. Motors can be mounted inline or reverse parallel to shorten the actuator. Tolomatic offers brushless servo and stepper motors or supply your own motor and take advantage of our “Your Motor Here” (YMH) program. Choose from 3 drive...

The factors that affect heat generation rate in an application are the pressure on the nut in pounds per square inch and the surface velocity in feet per minute. The product of these factors provides a measure of the severity of an application. Maximum Stroke 18 GSA(M) Size 12 Maximum Stroke 18...
