Typically, there are two bearing rings or races that the rolling element (ball, roller, or needle roller) is guided between. For radial bearings, there is a concentric inner ring and outer ring; each rotates around the same axis. For thrust bearings, the axis of rotation is also the same, but the rings are not concentric. Instead, they are mounted parallel to each other, with the rolling element sandwiched between them. Depending on the type of bearing, the races may have a raceway for the rolling element to ride in, a spherical radius, or a flat surface. Lower-precision bearing rings are simply machined while higher-precision bearings are ground to precise tolerances.
