Rolling bearing cage and other parts used materials

Rolling bearing in the work, the fever caused by sliding friction bearing wear. Especially under the condition of high speed, due to the effect of centrifugal force, accelerate the friction and wear with fever, a bracket will be caused serious burns and fracture, the bearing cannot be used properly. Therefore, to produce rolling bearing retainer materials in addition to have a certain strength, also must have good thermal conductivity, low friction coefficient, wear-resisting performance is good, the proportion of small and expansion coefficient close to rolling body. In addition, due to the complexity of cage structure is compared commonly, also the material has a good processing performance requirements. Commonly used bearing cage and rivet pillar materials are divided into ferrous metal materials ( Such as low carbon steel, stainless steel, etc. ) , non-ferrous metal materials ( Such as brass, bronze and aluminum alloy, etc. ) And non-metallic materials ( Such as phenolic fabric bakelite, plastic, etc. ) Three categories. Special-purpose bearing cage should also meet the requirements of special working conditions, such as high temperature resistance, corrosion resistance, self-lubrication ( Used in the vacuum) And no magnetic, etc. Black metal rolling bearing cage, for the most part, by 8 and 10 high quality carbon steel sheet cold stamping. In addition, the commonly used black metal materials and 20, 30, 45, 0 cr18ni9, 1 cr18ni 9 ti, S16SiCuCr, ML15, ML20, 65 mn, etc. Listed in table 6 - its purpose 2.
