Rollerscrews

Rollerscrews are mechanical components for the conversion of rotating motion to longitudinal movements and vice versa.
As rolling elements threaded rolls between the threaded shaft and the nut are arranged instead of balls (as in conventional ballscrews).
By the high number of contacts between rolls and races, rollerscrews are up to 15 times higher loadable than conventional ballscrews. The delivery program contains rollerscrews without roller feedback (series RV and BRV) and with roller feedback (series RVR) in several precision classes.
