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 ...

“B&R provided controls for a 65 meter long machine built by Brueckner in Germany that utilized a linear motor with track sections involving 728 sets of motor windings and over 700 linear motor movers.

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 ...

Knowing the details of a linear-motion application increases the odds of choosing the right ball screw. The more thrust an application requires, the larger the diameter screw will be needed. That’s ...
