Bearing Copper Cage is a bearing component that partially encloses the rolling elements and rotates with them. Its primary functions are to space and guide the rolling elements. The material is typically brass plate, casting, or forging.

Characteristics

Good thermal conductivity, low friction coefficient, excellent formability, relatively high maximum speed, and slightly lower lubrication requirements; Wear resistance and noise performance are superior to steel retainers, with mechanical strength comparable to steel plate stamping retainers, and not affected by commonly used bearing lubricants (including synthetic oil and grease).

Application scenarios

Commonly used in small and medium-sized bearings, such as self-aligning roller bearings and other types of bearings, it is suitable for scenarios with certain speed, temperature, vibration and other working conditions, but it is necessary to avoid uncomfortable environments such as high temperature and ammonia content.
