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. · 6 body sizes with built-to-order stroke lengths and mounting options · Stroke lengths up to 60 inches (1,524 mm) · Forces up to 13,039 lbf (58,001 N) · Acme, Ball, and Roller Screw options · IP67 option to protect against dust and water ingress · Flexible mounting options · Need faster delivery?
