Types of BearingsHow 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 ruining the

Rolling element bearingWikipedia
A rolling element bearing also known as a rolling bearing is a bearing which carries a load by placing rolling elements such as balls or rollers between two bearing rings called races.The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding. One of the earliest and best known rolling element bearings are sets of logs
