Ball BearingAball bearingis a type ofrolling-element bearingthat usesballsto maintain the separation between thebearingraces.The purpose of a ball bearing is to reduce rotational friction and supportradialandaxialloads.

Angular contact

Angular contact bearings better support "combined loads" (loading in both the radial and axial directions) and the contact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load.

Deep-grooveIn adeep-grooveradial bearing, the race dimensions are close to the dimensions of the balls that run in it. Deep-groove bearings can support higher loads.
