First of all, the contact fatigue
Turnover burden the cycle under the surface, it is easy to occur fatigue, cracked spalling is the main form of damage. Therefore, in order to make up for the contact fatigue life of rotation should be steel.
Second, the wear-resisting
Bearing, maintain and continuous evolution, not only including the flow of the ring friction equipment, and ensure the drilling SKF Bearings http://www.fagbearings-hk.com/ friction constant use of spare parts. Parts, in order to gradually reduce wear of bearings, the accuracy of the stable, longer-term work, should be gradually cut good abrasion resistant steel.
three
Stiffness concentration is the basic quality, quality, obtain NaiMoXing has direct influence to the fatigue limit, flexibility. In the use of bearing steel HRC61 hardness of situation usually - 65, contact and abrasion resistant fatigue.
Four, FangXiu
Bearing parts and finished goods, prevent within the framework of processing, storage and use of turnover, FangXiu than steel corruption should have good performance.
Five, treatment,
Turnover of spare parts in the process of production, after a lot of heat treatment process, to Jerusalem, to meet is very effective and high quality, bearing steel, has a good. For example, CuiTouXing refrigerants, cutting performance and so on.
Circulating funds in addition to the above basic steel, chemical composition, the United Nations must be appropriate, inequality of the internal implementation of various metal surface defect, and conforms to the standard of internal TuoTan floor does not exceed the prescribed limit, these projects focus on the standard of raw materials has clear rules.
Take turns to the material, which mainly are as follows: high carbon steel is commonly used spare parts with the refined steel, chromium steps (for example, 20 cr2ni4a 15 mn core, 20 cr2mnmoa), high temperature (such as thickness of steel of 16, Cr4Mo4V Cr14Mo4 bearing, W18Cr4V), Cr15Mo4V, 9 cr18mo, 9 cr18 (bearing, 1 cr18ni9ti), steel, steel, the vacuum of the magnetic rotation, is the most commonly used chrome steel bearing carbon-intensive. Chromium GangHao high carbon cut GCr6 essential GCr9 GCr9SiMn, steel, GCr15SiMn GCr15 bearing, flexibility, particularly in manufacturing, using GangZhong, efficiency, and resistant fatigue performance, processing desirable resistance against natural disasters.
