Bimetal bearing is a kind of oil-free lubrication bearing. It is based on high-quality low-carbon steel back and sintered with lead-tin bronze alloy on the surface. After several times of high-temperature sintering and dense rolling, a bimetallic strip of copper and steel is formed. Rolled, suitable for a variety of applications such as bushings and thrust washers that bear medium-speed and high-impact loads.
The balance bridge bushings of heavy-duty vehicles all use China bimetal bearings bushes, which is a kind of high-load and low-speed motion bearing with wide application. In the high sliding performance, it has particularly good self-lubricating performance in the absence of lubricating medium and water as the medium. It is suitable for bimetal casting materials, corrosion-resistant bearings with high sliding speed, and bearings for crushers, water pumps, and cold rolling mills. Piston pin sleeves with loads up to 70MPa.
The product has the advantages of good wear resistance. Especially suitable for medium speed, medium load and low speed and high load. Through special technical means, various oil grooves, oil pockets and oil holes can be machined on the friction surface to adapt to the use under different lubrication conditions. Mainly widely used in heavy-duty vehicle balance bridge bushings, gaskets, automobile steel plate bushings, internal combustion engine main bushes, connecting rod bushings, rocker arm bushings, oil pump side friction plates, medium and small power internal combustion engine bearings, train engine bearings, air Press sleeves, refrigerators, etc.
Since the base body is stable of low-carbon steel material, the machining accuracy of the outer diameter of the sleeve is guaranteed, and the product does not need to be fixed by screws after the product is installed in the seat hole, and the phenomenon of outer circle can be prevented by relying on interference fit. The change of the chemical composition of the inner surface alloy layer can meet the requirements of different bearing pressures, different operating temperatures, and different sliding speeds. The friction surface is designed with different structures of oil grooves and oil pockets in production to meet the requirements of different refueling methods and prevent biting. Axis phenomenon.
