Bearing steel is the steel used to make balls, rollers, and bearing rings. Bearing steel has high and uniform hardness and wear resistance, as well as a high elastic limit. The uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict, and it is one of the most stringent steel types in all steel production. The physical properties of bearing steel are mainly to check the microstructure, decarburization layer, non-metallic inclusions, and low-magnification structure. Under normal circumstances, they are delivered by hot rolling annealing and cold drawing annealing. The delivery status shall be indicated in the contract. The low-magnification structure of steel must be free of shrinkage cavities, subcutaneous air bubbles, white spots, and microscopic pores. Central porosity and general porosity shall not exceed grade 1.5, and segregation shall not exceed grade 2. The annealed structure of the steel should be uniformly distributed fine-grained pearlite.
The bearing steel sleeve is a reinforced product with extremely high compression resistance. When the graphite is embedded in the work and the lubricating particles are discharged, a layer of the diaphragm is formed between the shaft and the sleeve, which has a better anti-seizing effect than single oil lubrication. advantage. Especially suitable for supporting parts of hoisting machinery
