RVR Recirculating Roller Screws | Rollvis SA

A recirculating roller screw is a planetary roller screw because the rollers orbit the shaft. However, the inner mechanism is special. What makes the recirculating design different is that the rollers are ground with no thread angle and so they travel axially within the nut and reset — or recirculate — after each orbit. This type of operation provides exceptionally precise linear motion. A key to RVR roller screw operation is the carefully engineered cage that houses the grooved rollers and cam system which indexes the rollers precicely. The RVR design offers very high rigidity and we also offer preloaded designs when added axial rigidity is required.
