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 ...

Design refinements boost performance of self-aligning ball bushing while maintaining their error-correcting nature.

The amount of preload applied can be used to adjust the stiffness (and friction) of the bearing by changing the ball size to as small as 1 µm. Each application is a little bit different. For every ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

The accuracy of motion systems used in precision automation applications is significantly dependent on top-tier positioning stages and motion controllers. When designing a next-generation machine or ...
