Ball bearing retainers application

Ball bearing retainers are to preserve rolling element bearing stationary position, the role of ball bearing retainers are to make the roller in the bearing raceway is arranged at a fixed distance, prevent running bead, avoid biting each other between roller mill, rolling body is uniformly distributed along the circumference, at the same time reduce the bearing clearance in the run up to move brings adverse effects.  

Ball bearing retainers is a retainer which is used to hold the supporting part in the bearing and has a C-shaped concave for holding the supporting part. Between the pits is a connecting part closer to the opening of the pits. 
The rear of the adjacent two pits and the rear of the connecting portion used for the adjacent pits form a recessed part deeply dug into the retentionist. The bottom of the recessed part is closer to the opening than the bottom of the recessed part, thus allowing the base oil from the grease in the recessed part to better penetrate into the supporting part to lubricate the bearing.  
The material types of ball bearing retainers are: low carbon steel/stainless steel cage, bakelite/plastic (nylon) cage, brass/bronze/aluminum alloy cage, etc.  
When rolling bearings are working, sliding friction causes heating and wear of bearings. Especially under high temperature operation conditions, the effect of inertial centrifugal force intensifies friction, wear and fever. In serious cases, ball bearing retainers burns or fracture will be caused, resulting in the normal operation of bearings.  
Therefore, in addition to a certain strength, the cage material must also have good thermal conductivity, small friction coefficient, good wear resistance, strong impact toughness, low density and linear expansion coefficient close to the rolling body.
