The basic performance requirements of bearing steel

Release date:2020-6-16

Rolling bearing parts timber including timber and cage, rivets and other supporting material. The vast majority of rolling bearings and parts made of steel, bearing steel is usually high carbon chromium steel and hardened steel. With the increasing amount of development and the use of modern science and technology of rolling bearings, bearing the increasingly high demand, such as precision, long life and high reliability. For some special purpose bearings, bearing materials also requires a high temperature, corrosion-resistant, non-magnetic, ultra-low temperature, radiation and other properties. In addition, the bearing material further includes alloys, non-ferrous metals and non-metallic materials. In addition, the ceramic material of the bearing has been applied to locomotives, cars, subways, aviation, aerospace, chemical and other fields.

Rolling basic material requirements depends largely on the performance of the bearing. Select the manufacturer of rolling bearings material is appropriate, it will have a significant impact on its performance and life. Under normal circumstances, the main damage is in the form of a rolling bearing deposit under varying stress fatigue spalling, and wear due to friction loss leaving precision bearings. In addition, crack, indentation, corrosion and other causes of non-normal damage bearings. Therefore, the bearing should have a high resistance to plastic deformation, less friction and wear, good rotation accuracy, good dimensional accuracy and stability, and long contact fatigue life. And many of the performance is made of a material and heat treatment of the common decision.
