JF800 Bimetal bearing series




Introduction to materials

JF800 bimetallic bearing is made of steel back, the surface of sintered copper, tin alloy, rolled by the rolling of the sliding bearings, the standard alloy materials are: CuPb10Sn10, CuSn6Zn6Pb3, CuPb24Sn4, CuPn30, AlSn20Cu and so on. As the substrate stability for the low carbon steel material, so the sleeve diameter of the outer diameter of the processing accuracy has been guaranteed, and in the product into the seat hole does not require screw fixation, relying on interference with the interference can prevent the phenomenon of external; Chemical components can meet the different load pressure, different use temperature, different sliding speed requirements, the friction surface in the production of different structures of the oil tank, the oil can meet the requirements of different refueling methods, and to prevent bite axis phenomenon.

JF800 bimetallic application, must be designed with the conditions of oil lubrication, for high-speed low-speed rotation, swing movement. It is widely used in automobile balance bridge, spring steel plate hole, brake shoe, steering knuckle, moving connecting rod, punch sliding parts, bulldozer support, heavy wheel, gear box, oil pump, cylinder, engine, clutch and so on. Also widely used in mining machinery, steam cars, construction machinery, agricultural machinery, rolling machinery and so on.
