6. Rolling bearing type:

1 deep groove ball bearing, the most common type, mainly bearing radial load, can also bear a certain amount of axial load, compared with other types of bearings of the same size, such bearing friction coefficient is small, the limit speed is high.

2 Angular contact bearings, angular contact ball bearings have high limit speeds, can withstand radial and bearing loads, and can withstand pure axial loads. Their axial load carrying capacity is determined by the contact angle.

3 Thrust needle roller, thrust ball bearing, thrust ball bearing is a separate type bearing, the contact angle is 90 ° can only bear axial load, the limit speed is low.

4 self-aligning ball bearings, self-aligning ball bearings, self-aligning ball bearings have two rows of steel balls, two races on the inner ring, inner spherical shape on the outer ring, with self-aligning performance, can automatically compensate due to the shaft Concentricity error due to deflection. Applicable to parts where the support seat hole does not guarantee strict coaxiality.

5 Combination bearings, combined bearings are two or more types of rolling elements, used to withstand radial and axial loads or axial limit bearings.

6 Other bearings: cylindrical, tapered roller bearings, rubberized bearings
