Tolomatic RSA/RSM Electric Rod-Style Actuators
The RSA/RSM rod-style screw-drive actuator offers the most complete selection of sizes, options and system components. Designed with high performance, high thrust, dependability and mounting flexibility in mind, the RSA/RSM rod-style screw-drive actuator offers a cost-competitive solution for a multitude of motion control applications.
Available in inch (RSA) or metric (RSM) sizes
Specifications and Options
- Strokes in any incremental length up to 60”
- Maximum thrust up to 7000 lb
- Conforms to both NFPA and ISO industry mounting standards
- Temperature range from 40° to 130° F (4° to 54° C)
- Nickel plated ground steel thrust tube supports extremely high force and provides excellent corrosion resistance
- Multiple screw technologies available
- Solid nuts of bronze or engineered resins for quiet performance at the lowest cost, anti-backlash available
- Recirculating ball nuts for positioning accuracy, repeatability, and longer life, low-backlash available
- Roller nuts for the highest thrust and life ratings available
- High thrust bearing assembly eliminates runout and isolates linear forces from drive shaft, engineered resin bearing provides continuous support of screw
- Unique nose bearing material for smooth operation and support of thrust rod
- Engineered resin anti-rotation bearings support thrust tube and nut assembly through entire stroke length
- Internal bumpers protect the screw and nut assembly from damage at both ends of stroke
- Rod wiper protects housing from contaminant ingress for extended life
