Brass cage and steel cage in spherical roller bearing comparision:

The spherical steel roller bearing  retainer material requires the ability to withstand the vibration and impact load during operation, and the friction with the ring and the rolling body is small, lightweight and able to adapt to the operating temperature of the bearing.

Copper, Brass cage and steel cage for various ages.

1. The steel holder is stronger than the copper cage.

2. Small and medium sized bearings are generally cold rolled and hot rolled steel plates, which are also useful for brass and stainless steel plates.
The large bearings are usually made of car, and the materials are made of structural carbon steel ( S30C ) and high strength brass castings ( HBsCl ) , as well as ductile iron, aluminum alloy and other materials.

3. The anti-friction effect and wear resistance of copper are good.

4. than copper, steel retainer wear-resisting degree, and when the friction roller easy peeling, adhesion, and as magnetic materials, the use of residual magnetism after bearing itself is not easy to eliminate, wear after the iron due to residual magnetism is not easy to discharge, increased wear and tear.

Finished product waiting for washing and package.

Assemble the roller into cage, and assemble into rings.
