RSA Electric Linear Actuators
The RSA Electric Linear Rod Actuator combines excellent accuracy with a low-to-high thrust capacity in tough environments
RSA electric linear rod actuators feature accurate and high force performance, making them ideal for replacing pneumatic & hydraulic cylinders. These electric linear actuators feature acme, ball or roller screw selections, with enhanced high thrust bearings and heavy duty internal bumpers. A rigid, strong aluminum housing allows for easy mounting of switches and sensors. The standard grease zerk on HT units extends screw life by making relubrication easy and convenient without disassembly. RSA actuators are suitable for general motion control, valve actuation, punch press, injection molding and many more applications.
