Introduction to commonly used bearing models

Bearings are one of the common parts in mechanical equipment. They can support and rotate the rotating parts in the machine so that the machine can operate normally. In different machines, the types and sizes of bearings will also vary. Therefore, understanding commonly used bearing models is very important for the maintenance and repair of mechanical equipment.

Commonly used bearing models

1. Deep groove ball bearings

Deep groove ball bearings are one of the most common bearings and have the ability to withstand radial and axial loads. The model number of deep groove ball bearings starts with 6, such as: 600, 620, 630, etc.

2. Tapered roller bearings

A tapered roller bearing is a bearing that can withstand radial and axial loads. Its inner and outer rings are conical. The model number of tapered roller bearings starts with 3, for example: 30200, 30300, 31300, etc.

3. Self-aligning ball bearings

A self-aligning ball bearing is a bearing that can withstand large radial and axial loads and has the ability to self-adjust. The model number of self-aligning ball bearings starts with 2, such as: 220, 230, 240, etc.

4. Thrust ball bearings

Thrust ball bearing is a bearing that can bear axial load. Its inner and outer rings are spherical. The model number of thrust ball bearings starts with 5, such as: 51100, 51200, 51300, etc.

5. Thrust roller bearings

Thrust roller bearing is a bearing that can bear a large amount of axial load. Its rollers are cylindrical. The model number of thrust roller bearings starts with 8, such as: 81100, 81200, 89300, etc.
