Bearing processing and installation process and selection principles
1. Manufacturing process of bearing parts
The inner and outer rings are heat treated after forging or turning
The inner and outer rings are coarsely ground, finely ground, finally ground and then super-finished to the final size
Steel balls and rollers are formed by stamping, heat treatment, and machining
The holding ball is formed by punching and then finishing
2.Bearing assembly process
Various parts are demagnetized and cleaned, then the parts are sorted, grouped, and finally assembled, riveted, packaged and put into storage
Small bearings use automated production, large bearings require manual assembly
The cleanliness of the bearing is below 5μm
3.Principles for selecting bearings
In addition to the above basic working conditions, we may also need to provide you with the most suitable bearing according to your accuracy, clearance, cost, installation and disassembly, sealing, vibration, noise, friction torque and other requirements.

Where are slewing bearings used?Jul 17, 2024Slewing bearings, are extra-large rolling bearings consisting of an inner and outer annular seat ring and a rolling element, which are connected to the two parts of the structure of the machine or equipment that are rotating relative to each other to realise the relative slewing of the structure. Its field of application is very wide, covering almost all the need to withstand the combined load (including axial force, radial force and tilting moment) in the machinery and equipment.

What bearings are used in rolling mills?Jul 04, 2024The mill uses a variety of types of bearings, the specific selection needs to be based on the type of mill, working conditions and performance requirements and other factors for comprehensive consideration. In the selection of bearings, should give full consideration to its bearing capacity, limiting speed, precision requirements and lubrication and other factors, in order to ensure the stable operation of the mill and efficient production.
