Spherical roller bearings use rollers that are thicker in the middle and thinner at the ends; The race is shaped to match. Spherical roller bearings can thus adjust to support misaligned loads. However, spherical rollers are difficult to produce and thus expensive, and the bearings have higher friction than a comparable ball bearing since different parts of the spherical rollers run at different speeds on the rounded race and thus there are opposing forces along the bearing/race contact.

Quality Control:
1. Material GCr15 and eccentric casting of brass cage
2. Physical and chemical examination controls the metallurgical constituents of the material
3. Spectroanalysis instrument
4. Heat treatment-improves the life of the product
5. Foundry master and three coordinate measuring machine-ensures
