Linear Bearing: What Is It? How Does It Work? Uses, Types

Linear Ball Bearings. Linear ball bearings, or ball bearings, have spherical rolling elements (e.g., steel balls). They have low friction, longer service life, and high accuracy. They are the most popular type of rolling linear bearings. The spherical geometry allows them to be utilized in many linear bearing designs.

Rolling-element bearing - Wikipedia

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
