    Planetary Roller Screws

    Planetary roller screws convert rotary motion into linear motion. The drive unit is a roller between the screw and the nut, the main difference with ball screws is that the load transfer unit uses a threaded roller instead of a ball. Planetary roller screws have multiple contact points and can withstand large loads with very high resolution.
