What is a composite bearing?

The china composite bearing is one of the oil-free lubrication bearings. The product is based on high-quality low-carbon steel backing and the surface is sintered with a lead-tin bronze alloy. The composite bearing has been sintered and densely rolled for several times to form a copper and steel integrated double Rolled metal strip. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. It is especially suitable for heavy loads, low speeds, reciprocating or swinging situations where it is difficult to lubricate and form an oil film, and it is not afraid of water wash and other acid erosion. And scouring.

Since the base plate is stabilized as a 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 design of the friction surface in the production of different structures of oil grooves and oil pockets can meet the requirements of different refueling methods, and can prevent shaft biting phenomenon.
