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.

A Type-Thin section angular contact ball bearingsApr 30, 2024Compared with C-type bearing, A-type angular contact ball bearing has an enough radial clearance to form a sufficient contact angle to carry the axial load. The contact angle for the standard bearing is 30°.

CHG Bearing:Bearings for wind turbinesApr 16, 2024Blade bearings are used to connect blades with hubs in MW wind turbines, and they also can adjust the windward direction of blades to ensure electricity production with power rating and the safe work of wind turbines. Usually, single or double rows four-point contact ball slewing bearings are used as blade bearings, which have preload, special designed seals, anticorrosion surfaces,etc.

CHG Bearing:The lifespan of bearingsMar 28, 2024The bearing life refers to the number of revolutions or hours experienced by the bearing before the occurrence of pitting under a certain load. The life of rolling bearings is usually defined by the number of revolutions or the number of hours worked at a certain speed. During this lifespan, no initial fatigue damage (such as spalling or defects) should occur on any bearing ring or rolling element.

Assembly and disassembly of tapered roller bearingsMar 21, 2024Tapered roller bearings can be mounted directly on a tapered shaft or on a cylindrical shaft through an adapter sleeve or withdrawal sleeve. A tight fit is obtained by axially moving the inner ring. The tight fit of the inner ring can be effectively controlled by measuring the reduction in radial clearance caused by the expansion of the inner ring.
