Track-roller linear guides and how they compare to other linear rails, slides, and ways to facilitate single and multi-axis linear motion — and the disparate ways these linear components integrate ...

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 ...
