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 ...

Planetary roller screws provide significant benefits over other screw-type actuators in terms of performance, load capacity, duty cycle, and lifetime. Traditionally, however, those benefits have come ...

The components get assembled into a planetary gearhead with a roller chain replacing the traditional ring gear. They are assembled into a complete gearhead from Gearing Solutions. Durable gears for ...

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 ...
