Rolling composition

Rolling due to different purposes and working conditions, many of its structural changes, but the basic structure is a composite bearing inner ring, outer ring, rolling elements (balls or rollers) and cage four parts. (1) an inner ring (also known as the inner sleeve or inner ring). Usually fixed to the journal, the inner ring rotates together with the shaft. Inner or outer surface for roller ball rolling grooves, called the groove or the inner race. (2) the outer ring (also known as jacket or outer). Usually fixed on the bearing housing or machine sliding bearing housing, from the rolling elements supporting role. On the outer surface of the circle there for the ball or roller rolling grooves, called the groove or the inner race. (3) rolling elements (balls or rollers). Each bearing is equipped with a group or several groups of rolling elements disposed between the inner and outer rings, each passing from rolling forces. Rolling body is subjected to a load of parts, their shape, size and number of the decision to bear the load bearing capacity of each high speed performance. (4) holder (also known as the holder or isolator). The bearing rolling elements evenly spaced so that each rolling element rolling normally between inner and outer rings. In addition, the retainer having a guide rolling body movement, improve the bearing internal lubrication conditions, and to prevent rolling off the body and so on. In the thrust bearing, and the shaft with ferrule called shaft washer, and housing or machine casing box office with ferrule, shaft ring and seat ring gasket collectively. In addition to these four components, the various configurations of its bearings as well as other parts of the match. For example, rivets, shield, seal, washers, retaining rings and tight sets and the like.
