Bearings are important components in mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission of the equipment.Bearings are divided into radial bearings and thrust bearings according to different bearing directions or nominal contact angles.

According to the type of rolling element, it is divided into: ball bearing, roller bearing.

According to whether it is self-aligning, it is divided into: self-aligning bearings, non-aligning bearings (rigid bearings).

According to the number of rows of rolling elements, it is divided into: single-row bearings, double-row bearings, and multi-row bearings.

According to whether the parts can be separated, they are divided into: separable bearings and non-separable bearings.

In addition, there are classifications by structure shape and size.

We are mainly talking about angular contact ball bearings and thrust bearings.

There is a contact angle between the ring and the ball. The standard contact angles are 15°, 30° and 40°. The larger the contact angle, the greater the axial load capacity. The smaller the contact angle, the more conducive to high-speed rotation. Bear radial load and unidirectional axial load. The two single-row angular contact ball bearings that are combined in structure on the back share the inner ring and the outer ring, which can bear radial load and bidirectional axial load.

The main purpose:

Single row: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, front wheel of small car, differential pinion shaft.

Double row: oil pump, roots blower, air compressor, various transmissions, fuel injection pump, printing machinery.

Thrust ball bearing

It is composed of a washer-shaped raceway ring with a raceway, a ball and a cage assembly. The raceway ring matched with the shaft is called the shaft ring, and the raceway ring matched with the housing is called the seat ring. The two-way bearing is matched with the secret shaft in the middle ring, the one-way bearing can bear one-way axial load, and the two-way bearing can bear two-way axial load (neither can bear radial load).

Main application: automobile steering pin, machine tool spindle.
