Ball screws and roller screws are widely used for high-force linear motion and are replacing fluid power devices. In general, these screw mechanisms generate linear motion by rotating either the screw ...

Armed with even with the most-sophisticated motion controller, engineers can still find it difficult to attain precise linear motion unless the mechanical components are appropriately designed for the ...

Essentially, a guide wheel is a ball bearing that has a special shaped outer race. The inner and outer races of ball bearings are a framework with a groove for the balls to rest in. Burke explained ...
