Standard Roller Screws with HRB (HRA-S)
The HRA-s combines a standard roller screw with HRB bearing integrated on the screw shaft. The bearing inner ring is machined on the screw shaft saving weight and optimizing size by avoiding unnecessary flange and locking devices. By maximizing capacity and reliability, the HRA – s offers unprecedented power density with a custom mechanical package ready for the next generation of electric linear actuators.
The optimized compact integrated linear solution.
