Roller Screw Jack Actuators

SKF Roller Screw Jack Actuators (RSJA) employ an SKF spherical roller thrust bearing that supports a roller screw nut. By using rollers as rolling elements the system permits lowering and raising of heavy loads with high efficiency and high reliability. It provides an overall efficiency as high as 70 % in some models depending on the ratio of the worm gear set.

Main benefits

• Move loads and apply forces more efficiently and more reliably than all other types 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.

Applications

In steel industry, for continuous casting machines.
