Available in diameters from 3.5 to 150mm, Exlar PRS Series roller screws provide solutions to a wide range of applications - from the most compact and precise to the largest and extremely high load requirements.
This robust roller screw design is composed of rollers that are manufactured with precisely the same thread angle as the nut. This construction is particularly well-suited to applications that require very high loads and high speeds. This is possible because Exlar's planetary roller screw designs provide many more contact points than possible on comparably sized ball screws. The result is higher stiffness, higher load capacity and 15 times the travel life of similarly sized ball screws. The diagram at right shows the number of contact points in a ball screw compared to the number of contact points in a roller screw.
