The relationship between the high temperature bearing material and performance

High temperature bearing materials and properties of the relationship between the rolling bearing ring and churning, side repeatedly suffer high touch pressure, side stop along with a sliding of the touch. Insist, one side and on either side of the ring and roll body, or its one side sliding touch, side suffered tension and shorten the force. Therefore, the bearing ring, churning body and adhere to the frame of the data and function. Ring, churning the function of the body materials have begged: churning fatigue strength high hardness, high resistance to friction consumption insists on the function of rack profile and begged: dimension stability good mechanical strength, in addition, also need good workability. According to use, and begged the impact resistance, heat resistance, good corrosion resistance. Ring and churning body materials: ring and churning body usually use high carbon chromium bearing steel. Big local bearing, using JIS SUJ2 steel grade. Use SUJ3 large high temperature bearing. The chemical composition of SUJ2, around the world, as the sliding bearing with data has been normalized. For example: with AISL52100 ( The United States) DIN100Cr6 ( West Germany) BS535A99 ( The UK) All belong to the same steel. Further impact resistance under the condition of demand, as a bearing material using nickel chrome steel, chrome molybdenum steel, chrome molybdenum steel, using carbon quenching, make the steel from appearance to the appropriate depth has a soft layer. With proper softening depth, fine layout, appropriate hardness hardness of appearance and the core permeability coal bearing, than using the bearing steel bearing has excellent resistance to impact, single permeability coal bearing steel chemical composition. Implemented vacuum degassing treatment, therefore, the use of data cleaning degree is high, less oxygen content, good quality. Then use the appropriate heat treatment, the bearing of churning exhausted life spans a significant amount of progress. The steel grade, on the basis of particularly useful, also with good heat resistance of high speed steel, good corrosion resistance of stainless steel. Adhere to the frame data: stamping adhere to the frame of the data, using low carbon steel. According to use, also use brass, stainless steel plate. Sliced adhere to the frame of the data, using brass, carbon steel, high strength, moreover also USES the differentiation of resin.
