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.
Application of rolling mill bearingsFeb 28, 2024Rolling mill bearings should be selected according to the type and working characteristics of the rolling mill. 1. Billet opening machine and billet mill: This type of rolling mill generally has a large rolling force and strong impact load, but the speed is not high;
CHG Bearing:High quality rollers-rolling elementJan 25, 2024CHG Bearing can produce all kinds of high-precision cylindrical and tapered rollers in the range of φ15mm to φ160mm in diameter and 20mm to 220mm in length, with an annual output of 10 million pieces and product precision up to G1 and G1A (Grade I) standards. More than 150 sets of various precision equipment, and various perfect special testing instruments, ultrasonic flaw detection (UT), magnetic particle flaw detection (MT), eddy current flaw detection (ET) instruments, spectrometer, carbon and sulfur analyzer, roundness meter, contour roughness meter, etc.
Types of thin-section bearingsDec 29, 2023Firstly, Thin-walled ball bearings with equal cross-sections. Secondly, Crossed roller bearings of equal cross-section have cylindrical rollers arranged crosswise on the V-shaped raceway, and the rollers are separated by isolation blocks.
Structure and features of CHG precision ball bearing 618 619 seriesDec 14, 2023The deep groove ball bearing is a kind of rolling bearing with most representatives, and it has features of small friction coefficient, high limiting speeds, simple structure, low cost, and high manufacturing precision. It has various sizes and structures, and is used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, and a kind of bearing with most applications in the machinery industry. The bearing can bear mainly the radial load, but also can bear a certain axial load.
