Composite bimetal Bearing is a non-oil lubricated bearing, the product is a high-quality low carbon steel back as the matrix, the surface of sintered Lead-tin bronze alloy, after several high-temperature sintering and dense rolling of copper, steel-based bimetal strip Coil.
It has high load-bearing capacity, impact resistance, High temperature, self-lubricating capacity and other characteristics, especially suitable for heavy-duty, low-speed, reciprocating or oscillating, such as difficult to lubricate and form oil film, but also not afraid of water and other acid leaching and erosion. As the substrate stability for Low-carbon steel material, so the outer diameter of the sleeve processing accuracy has been guaranteed, and in the product installed seat hole without the need for screw fixation, relying on interference fit can prevent the outside circle Phenomenon.
The chemical composition of the inner alloy layer can meet the requirements of different bearing pressure, different use temperature, different sliding speed, the friction surface in the production of different structure of the oil groove, oil points can meet the requirements of different refueling methods, and can prevent the phenomenon of biting. Composite bimetal bearing has the advantages of good abrasion resistance, especially suitable for medium-speed medium load and low-speed high current carrying and other Occasions. A variety of oil grooves, oil points and oil holes can be machined on the friction surface, thus adapting to the use under different lubrication conditions. Products are mainly used in heavy-duty car balance bridge bushings, gaskets, Automotive engines, chassis, motorcycle clutches, Gear Pump wiping plate and lifting equipment and other FIELDS.
