How are bearings named?

For those who frequently come into contact with machinery, they know that the role of bearings cannot be underestimated. But many people are still confused about the relevant knowledge and functions of bearings. Today, the editor will give you a brief introduction.

Definition of bearings:

Compared to large machinery, bearings are small components but play a crucial role.

And it is mainly a component that fixes and reduces the friction coefficient of the load in the mechanical transmission process. When other components generate relative motion on the shaft, bearings can be used to reduce the friction coefficient during power transmission and maintain the fixed position of the shaft center. According to the different friction properties of the moving components, bearings can be divided into rolling bearings and sliding bearings.

Bearing type:

According to the different functions, designs, and functions of bearings, there are many types of bearings, including needle roller bearings, self-aligning ball bearings, deep groove ball bearings, self-aligning roller bearings, thrust bearings, seat bearings, joint bearings, combination bearings, rolling mill bearings, etc. Different bearings have different functions and play an important role in different mechanical equipment.

Bearing code

A complete bearing code consists of a basic code, a pre code, and a post code, and is arranged in the following order: pre code, basic code, and post code.

A. Pre code refers to the use of letters to distinguish bearings when there are changes in their structural shape, dimensions, tolerances, technical requirements, etc;

B. The basic code is used to indicate the basic type, structure, and size of bearings, and is the basis of bearing codes. Electric vehicles use deep groove ball bearings, which consist of three basic codes: bearing type code, size series code, and inner diameter code: type code, size series code, and inner diameter code.
