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 ...

Download the PDF of this article. In high-throughput applications, standard triangular or trapezoidal motion profiles have been widely utilized to reach a desired position quickly. As shown in the ...

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 ...

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.
