RSA-HT Heavy Duty Electric Linear Actuators

Heavy duty electric rod actuator ideal for applications requiring high force performance in tough environments.

The RSA-HT heavy duty electric rod actuator accommodates larger motors and delivers high force with excellent accuracy. These high force electric linear actuators feature ball or roller screw selections, an enhanced high thrust bearing and heavy duty internal bumpers. The standard grease zerk extends screw life by making relubrication easy and convenient without disassembly. RSA-HT actuators are suitable for valve actuation, punch press, injection molding applications and many more.
