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 ...

This article will examine several examples of how to select the appropriate linear bushing for the application. Impact on performance from material and surface treatments will be discussed.

Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...

Machines that turn, eject, cut, and spray rely on efficient, automatically reversing linear motion. Rolling-ring linear drives are commonly used in these types of applications because they eliminate ...

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.

Super smooth: the updated linear-shift mechanism from UHV Design exploits a precision slideway to increase the translation speed (Courtesy: UHV Design) UHV Design, which specializes in the design, ...

For Hackers, rapid prototyping is made easier using basic building blocks such as the Raspberry Pi, Arduino and the huge variety of add on shields for home brew projects. But we don’t see too many ...
