Linear guide provide a type of motion that utilizes re-circulating rolling elements between a profile rail and a bearing block.
Ballscrews consist of a screw spindle and a nut integrated with rolling elements that cycle through a return mechanism.
A planetary roller screw is a mechanism that converts rotary motion into linear motion, the load transmission element is a threaded roller, which is a line contact, so that a higher load can be achieved.
Linear modules combine various components into a single actuation unit that generally requires the end user to add drive motor and control. These Linear modules incorporate various components that can be mixed and matched to suit the applications requirements.
