RSA-ST Electric Linear Rod Actuators
The RSA-ST electric linear rod actuator combines excellent accuracy with a low-to-medium thrust capacity
RSA Quick Ship Program – Fixed stroke RSA32ST available in one week! Limited supply available
RSA-ST electric linear rod actuators feature accurate, medium force performance making them ideal for replacing pneumatic cylinders. High thrust bearings and internal bumpers deliver heavy duty performance. A rigid, strong aluminum housing allows for easy mounting of switches and sensors. These electric linear rod actuators are suitable for pneumatic replacement, general motion control applications and many more.
