1、 Definition and function of bearings

Bearings are important mechanical components that are installed between shafts and frames to support and rotate. Its function is to support and rotate the shafts and accessories in the machine. In mechanical transmission, bearings play a role in supporting, reducing friction, and lowering energy consumption.

2、 Types of bearings

1. Deep groove ball bearings: Deep groove ball bearings are the most widely used type of bearing, characterized by simple structure and easy use. They are widely used in various machine tools, electrical machinery, household appliances and other equipment.

2. Angular contact ball bearing: Angular contact ball bearing is a special type of bearing that can withstand large radial and axial loads. Widely used in high-speed motors, automotive transmissions, aircraft spindles, and other equipment.

3. Conical roller bearing: Conical roller bearing is a type of bearing that can withstand large radial and axial loads, and is widely used in fields such as automobiles and heavy machinery.

4. Self aligning roller bearing: Self aligning roller bearing is a type of bearing that can adjust the inclination of the spindle and withstand large loads. Widely used in heavy machinery such as steel, mining, printing machinery, generators, etc.

5. Thin diameter roller bearings: Due to their compact structure and strong load-bearing capacity, thin diameter roller bearings are widely used in fields such as automobiles, motorcycles, and air conditioning compressors.

6. Sliding bearings: Unlike rolling bearings, sliding bearings convert frictional force into hydraulic pressure through a lubricating oil film to withstand loads, and are widely used in fields such as motorcycles, automobiles, and ships.
