Rollvis RVD Series Differential Planetary Roller Screws
Rollvis RVD differential planetary roller screws use two nuts with slightly different leads preloaded against each other via an adjusting nut, delivering high rigidity and near-zero axial play (≤0.02 mm). With no recirculating parts they run quietly at high speed, at 80-95% efficiency. Shaft diameters 6.35-32 mm, leads 0.525-10 mm, dynamic ratings 21.6-616 kN, static 39.7-1140 kN, speeds up to 8000 rpm, 6-12 roller circuits, standard lengths 100-280 mm up to 2500 mm max, with hollow-shaft and through-shaft options for servo cylinders and humanoid linear joints.
