Vendor: Rollvis
Product: RVR 循环式行星滚柱丝杠
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.
