Types of Bearings - How Bearings Work | HowStuffWorks

Oct 11, 2000· 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 bearing is overloaded, the balls can deform or squish, …

How Ball Bearings Work - Allied Caster

Feb 09, 2018· A ball bearing works when, with the assistance of lubriion, the enclosed balls experience a state of continuous motion. They keep their consistent rotation due to the retainer that keeps the balls an equal distance apart and secured within the bearing while allowing them to still spin freely.

Angular Contact Ball Bearings - an overview

Angular contact ball bearings (Fig. 35.13) In angular contact ball bearings the line of action of the load, at the contacts between balls and raceways, forms an angle with the bearings axis. The inner and outer rings are offset to each other and the bearings are particularly suitable for carrying coined radial and axial loads.
