Roller Screw Jack Actuators
Main benefits • Move loads and apply forces more efficiently and more reliably than any other type of mechanical actuators • Enable faster operation and longer travel under high load • Require less power • Transmit high power without overheating
• Ensure correct functioning even in adverse environments such as dirt or poor lubrication. Consult SKF. • Robust design to withstand shock loads.
