INTRODUCTION TO BEARINGS AND DEFINITIONS | PPT

 — 15. Ball bearings • In a ball bearing, the load is transmitted from the outer race to the ball and from the ball to the inner race • Since the ball is a sphere, it only contacts the inner and outer race at a very small point, which helps it spin very smoothly • But it also means that there is not very much contact area holding that load, so if the …

Lead Screws 101 To help explain the theory of operation …

screw can be ignored which simplifies the screw to a ramp that is wrapped around a cylinder, thus creating a helix. In this case the lift becomes the linear motion component of the screw, and run becomes the rotation of the screw as noted in Figure 1. The lead of the screw is defined as the linear distance traveled per rotation of the screw.
