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.
Rollvis (Switzerland) RVR recirculating planetary roller screws achieve 1-2 micron positioning accuracy and very high repeatability with leads as small as 0.25 mm/rev; shaft diameters 8-125 mm, leads 0.25-5 mm and dynamic load ratings 7.3-986 kN in a smaller nut diameter. All-metal construction with precision-ground nuts, rollers and shafts; low input torque to drive and hold loads with back-drive resistance and very high rigidity, ideal for precision positioning, telescopes, downhole tools and grinding machines.
TBI Motion SCI/SCNI precision ground ball screw series covers shaft diameters Ø16-80 mm with leads 4-10 mm; dynamic load rating up to 7346 kgf, static up to 31953 kgf and axial stiffness up to 109 kgf/μm; SCNI uses longer nuts for higher load capacity with dual-circuit recirculation for smooth running - built for machine tools, injection molding and heavy robot axes.
