The Rollvis RVR satellite roller screw is a design with recirculating rollers. The rollers are guided within a cage and their motion is controlled by a set of cams.
This design combines extremely high positioning accuracy, resolution and stiffness while capacity ratings are at the highest thanks to a robust thread geometry. This concept is perfect for all applications that need a very high accuracy under small or moderate speeds.
