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
