Bearing manufacturing:
Bearing inner ring and outer ring processing varies according to the difference of the raw materials or blank forms, including car before machining process can be divided into the following three, the whole process is: the bar stock or tube (some bar need to the forging, annealing, normalizing) - car processing, heat treatment, grinding, grinding or polishing final inspection - rust - - parts inventory --

Raw materials for high quality bearing forgings:
Contact fatigue strength
Bearing steel must have high contact fatigue strength.
Wear resistance
Bearing task, not only between the ring, the rolling body and the support frame will occur rolling friction, but also will occur sliding friction, so that the bearing parts have been worn. In order to increase the wear of bearing parts, maintain the stability of bearing precision and extend the service life, bearing steel should have good wear resistance.
Three, hardness
Bearing steel in the use of individual hardness to reach HRC61~65, the ability to make the bearing to obtain higher contact fatigue strength and wear resistance.
Rust resistance
In order to avoid bearing parts and finished products in the process of processing, consignment and use of rust corrosion, request bearing steel should have good rust resistance.
processing performance
Bearing processing:
In the bearing production process, the most critical links are as follows:
(1) forging
Forging is an important link to ensure the reliability and life of the bearing. At the same time, the structure of the raw material becomes denser and the flow linearity becomes better, which can improve the reliability and service life of the bearing. In addition, the quality of the forging process will also directly affect the utilization rate of raw materials, thus affecting the production cost.
(2) heat treatment
Heat treatment is to process the forged and machined bearing ring at high temperature, which directly affects the uniformity of carburizing in the bearing ring, improves the wear resistance and hardness of the bearing, and also affects the reliability and service life of the bearing.
Bearing assembly:
Integral sliding bearing commonly known as the shaft sleeve, a kind of form is also the most simple of the sliding bearing, mainly adopt the method of pressure into and hammer to assembly, special occasions with hot pack, most of the collar is made of copper or iron, should be careful when assembling, use wooden hammer or hammer cushion block and the method of assembly and interference with press pressure into the larger size tolerance. No matter knock or press must prevent tilting, after assembly, oil groove and oil hole should be in the required position.
