A bearing is a machine element that constrains relative motion and reduces friction between moving parts to only the desired motion. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Many bearings also facilitate the desired motion as much as possible, such as by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts.
- Angular Contact Bearings - Review Angular contact bearings are constructed such that their races and the bearing balls contact points are at some angle relative to the axis of the operating axis of the bearing.
- Angular / Radial Contact Ball Bearings Static Load Rating Static load rating for Angular / Radial Contact Ball Bearings, use the following the equation:

- Ceramic Bearings Ceramic bearings offer many advantages over all steel bearings, such as higher speed and acceleration capability, increased stiffness, lower friction and more.
- Critical Speeds of Rotating Shafts or Mass Review The center of a rotating mass is always offset from the center of rotation. This is due to the reality of imperfect geometry and uneven mass distribution.
- Critical Speeds of Rotating Shafts with Single Loads When calculating critical speeds, the weight or mass of the rotating cylinder or shaft is assumed to be zero or add 1/2 to 2/3 of the rotating shaft to the load mass.
