Inverted Roller Screw

Inverted Roller Screw is a specialized precision mechanical manufacturer dedicated to high-performance inverted planetary roller screw mechanisms and electromechanical actuation solutions.

Unlike standard roller screws where the nut moves along a rotating threaded shaft, inverted roller screws integrate the nut as the primary rotor or casing while the shaft translates axially. This architecture provides unmatched power density, exceptional axial load carrying capacity, ultra-compact stroke integration, and extended operational lifespan under extreme industrial operating conditions.

Our engineering team delivers custom engineering, precision thread grinding, preload optimization, and turnkey linear actuator assemblies for robotics, aerospace, medical technology, defense, and high-duty industrial automation applications.
