Roller screw jack
ø 3.5 - 100 mm, 1.0 - 30 mm
KML Linear Motion Technology GmbH
As rolling elements threaded rolls between the threaded shaft and the nut are arranged.
By the high numbers of contacts between rolls and races, rollerscrews are very highly loadable. Our delivery program contains rollerscrews without roller feedback (series RV and BRV) and with roller feedback ( series RVR) in several precision classes.
