automotive bearings

Automotive Bearing Introduction: one of the two members of the class of rolling, or so-called antifriction, bearings (the other is the roller bearing). The function of a ball bearing is to connect two machine members that move relative to one another in such a manner that the frictional resistance to motion is minimal. To minimize friction, the contacting surfaces in a bearing may be separated by a film of oil or gas; these are sliding bearings (see oil seal). In ball bearings and roller bearings, the surfaces are separated by balls or rollers
