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 ...

A linear actuator combines linear-motion components and a linear shaft motor (direct drive) in one assembly. Such an actuator creates motion in a straight line, in contrast to the circular motion of a ...

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 ...
