* Heat generated by the motor and drive should be taken into consideration as well as linear velocity and work cycle time. For applications that require operation outside of the recommended temperature range, contact Tolomatic.

LARGE FRAME MOTORS AND SMALLER SIZE ACTUATORS: Cantilevered motors need to be supported, if subjected to continuous rapid reversing duty and/or under dynamic conditions.

SIDE LOADING CONSIDERATIONS: Rod screw actuators are designed to push guided and supported loads and are not meant for applications that require substantial side loading. Please contact Tolomatic for details regarding side loading capabilities.

Additional RSA information

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.
