Low-friction, high-stiffness ball guides support on one rail (top) or two (bottom). The trade-offs for this performance are higher cost and more noise. The shortest path between two points is a ...

The MLA (motorized linear actuator) and MEA (motorized electric actuator) series represent a new generation of compact linear motion solutions. Each actuator combines a high-performance stepper or ...

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 ...

Back in the 1980s, Pacific Bearing Co. (PBC) invented and commercialized plain bearings, which were sized to be interchangeable with linear ball bearings. Plain bearings worked very well in certain ...
