Bearing Basic Knowledge

1. What is the bearing?

Parts in the mechanism that support or guide through the positioning of moving parts relative to other parts, or the part supporting a relatively rotating shaft is called a bearing. Usually, the axis rotates, there are also shafts that do not rotate but the shell rotates, such as car hub bearings.

2. What is the axis unit?

Bearing functional parts (or components, assemblies, etc.) formed by integrating other relevant functional parts and components with bearings as core parts. Such as automobile hub bearing unit, machine tool spindle bearing unit, ball screw bearing unit, etc. Spindle bearing units include spindle bearings, shells and some fasteners. Spindle bearing units can be purchased according to the type, size, installation method, accuracy, stiffness, rotation speed, etc. of the machine tool. With the development of science and technology, in order to save materials and space, improve accuracy, reduce costs, reduce design and production cycles, and meet the needs of mainframes, bearings develop forward combination and unitization.

3. What is the combined roller bearings?

Bearings composed of different types of bearings. Such as needle and thrust ball combination bearings, needle and angular contact ball combination bearings, needle and bidirectional angle contact ball combination bearings, needle and thrust cylindrical roller combination bearings, needle and bidirectional thrust cylindrical roller combination bearings, etc.

4. How many grades are there in the production of bearing?

Product categories are divided into five grades: large categories, small categories, series, varieties, and specifications. The classification of product categories is used as a unified basis for the planning and statistical management of the mechanical industry and stipulated in accordance with standards. The classification of products is divided according to the main functional characteristics of the product, among which rolling bearings is a big category. According to the technical standard system of the rolling bearing industry, the bearing products at the entrance of the rolling bearing industry are divided into three categories: rolling bearings, joint bearings and linear motion rolling support. Among them, rolling bearings and linear motion rolling supports belong to the rolling bearing type, and joint bearing belongs to the sliding bearing type.

5. What is the rolling bearing?

The International Organization for Standardization defines rolling bearings as rolling (not sliding) between parts that bear loads and move relative to each other. It includes parts with raceways and rolling body groups with or without isolation or guidance parts. It can be used to withstand combined radial, axial or radial and axial loads.
