Deep groove ball bearing due purposes and working conditions are different, there are many changes in its structure, but the basic structure is from the inner ring, outer ring, rolling elements (balls) and cage four parts.
An inner ring (also known as the inner sleeve or inner ring). Normally fixed in the journal, the inner ring rotates with the shaft. The outer surface of the inner ring with balls or rollers for rolling grooves, called an inner groove or inner raceway.
Second, the outer ring (also known as a jacket or outer ring). Normally fixed to the bearing housing or the housing of the machine, from the effect of the rolling element bearing balls. Surface of the outer ring also has a ball or roller for rolling groove, called internal or inner raceway groove.
Third, the rolling elements (balls). Each groove ball bearings are equipped with one or more groups of rolling elements, mounted between the inner and outer rings, the transfer from the rolling force. The rolling body is the load bearing part, the shape, size and number determines the load capacity of the bearings are subjected to high speed performance.
Four, the cage (also known as cage or isolator). The bearing of the rolling bodies evenly spaced, so that each rolling element between the inner ring and the outer ring rolling normally. In addition, the cage has guided rolling motion, improve internal bearing lubrication conditions and to prevent rolling off and so on.
In the thrust ball bearing, and the shaft with ferrule called shaft washer, and housing or machine casing with ferrule box office, shaft ring and seat ring gasket collectively. In addition to the four parts, the various configurations of the bearing and other parts of its mating. For example, rivets, dust cover, seals, washers, retaining rings and tight sets and so on.
