 The type of Bearings retainer 

In general, the bearing cage is made of soft material and low carbon steel is preferred. In high temperature or damp, corrosion environment and complicated operation condition using stainless steel, nylon, phenolic resin, and the cage material such as iron, copper, but there is little use in the car.

The role of cage is to make the rolling element bearing raceway in the 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 bring adverse effects in the run up to move; When not in use, full bead arrangement can be chosen to extend bearing life or enhance bearing precision.

The preferred soft material of the holder is to avoid aggravating the wear of the rolling body in the bearing and to extend the service life of the bearing. However, in complex environment, due to low carbon steel's poor anti-oxidation, anti-corrosion and high-temperature resistance, it cannot be used normally, so other materials listed above are used.
