Imported bearing materials and the relationship between the performance

Imported bearing materials and properties of the relationship between the rolling bearing ring and rolling body, side again and again under high contact pressure, accompanied by sliding of rolling contact. Retainer, one side and on either side of the ring and rolling body, or its one side sliding contact, one side under tension and compression force. Therefore, the imported bearing ring, rolling element and cage materials, properties, main requirements are as follows. Ring, rolling body materials required by the performance: rolling fatigue strength high hardness, high resistance to friction consumption cage materials required by the performance: the size stability, good mechanical strength and good workability. According to different purposes and demands of its, impact resistance, heat resistance, good corrosion resistance. Cage materials: punch retainers material, using low carbon steel. According to different purposes, also used brass, stainless steel plate. Cutting system maintains a material, the use of high-intensity brass, carbon steel, and also the use of synthetic resin.
