Introduced bearing materials
Inner and outer rings of bearings, ball bearing steel for the material (vacuum heat treatment). Most of the bearings, the use of JIS steel SUJ2, that is, domestic chrome steel (GCr15). SUJ2 chemical composition, in the world, as bearing materials have been standardized. For example: with AISL52100 (United States), DIN100Cr6 (West Germany), BS535A99 (United Kingdom) are the same species, such as steel. The use of the material, effectively improve the performance of the bearing torque, lower noise, extension of life expectancy. However, in humid or high temperature environment, requires the use of martensitic stainless steel material.
