As the RV planetary roller screw shaft rotates, the rollers, which are in contact with both the screw’s threads and the nut’s threads, also rotate and move in a planetary (orbiting) motion around the screw shaft, converting rotary motion into linear motion. Roller screws can outperform ball screws in nearly every category.
The HRV Series, heavy duty planetary roller screws, starts from shaft diameter 60mm and offers and even greater load capacity.
