Here’s a little engineering quiz for you: If an app needs to move a 500 kN axial load along a 1,500 mm stroke, is it best to use a roller screw or ball screw? If you instinctively said roller screw, ...

Planetary roller screw mechanisms (PRSMs) are advanced mechanical devices that convert rotational motion into precise linear displacement. Their design capitalises on an array of rolling elements ...

The PRS models, with G5 lead accuracy, are available in screw diameters ranging from 8- to 80-mm, and deliver static load ratings up to 218,000-lbf. Exlar’s PRR models, with G9 lead accuracy, are ...

Select appropriate bearing types and designs based on load direction, contact pattern, and environmental factors to ensure longevity and reliability. Recognize the advantages of roller bearings over ...
