Bimetal bearings, specifically cylindrical bearings, can be ordered in a variety of materials. A popular choice is a combination of steel backing with a lead-bronze sliding layer. The lead-bronze layer, which typically consists of approximately 80% copper (Cu), 10% lead (Pb), and 10% tin (Sn), is sintered to the steel backing. This specific lead-bronze alloy is commonly referred to as CuPb10Sn10. This material composition enables smooth sliding and provides excellent wear resistance and durability. The sliding layer often includes lubrication indents to further enhance the bearing’s performance. These bearings are available in a standard range of sizes, including cylindrical wrapped bushes and thrust washers in metric dimensions. Non-standard parts, strips, and special forms can also be ordered to meet unique requirements. In addition to metric sizes, they can also be ordered as inch bushes, strip, and special forms. Bearings of this type, including washers, are also available for order. Their versatility and customizable nature make them an excellent choice for a wide variety of applications.

Bimetallic bearing is one of the bearing lubrication systems and the product is high-quality low carbon steel back as substrate, the bronze alloy on the surface, through several high-temperature sintering and density and rolled copper and steel bimetallic strip coiling, suitable for medium and high impact load under bush and thrust washer and so on many kinds of USES.

Overview of bimetallic bearings 

Bimetallic bearing is one of the bearing lubrication systems, the product is high-quality low carbon steel back as substrate, the bronze alloy on the surface, through several high-temperature sintering and density and rolled copper and steel bimetallic strip coiling, suitable for medium and high impact load under bush and thrust washer and so on many kinds of USES.

Bimetallic bearing steel material

Because the matrix is stable as low carbon steel material,so that  the machining accuracy of the outer diameter of the shaft sleeve is guaranteed. Moreover, after the product is loaded into the seat hole, there is no need for screw fixation. By The change of chemical composition of the alloy layer on the inner surface can meet the requirements of different bearing pressure, different operating temperature, and different sliding speeds. The oil groove and hole with a different structure designed on the friction surface in the production can meet the requirements of different refueling methods and can prevent the phenomenon of biting the shaft.

Bimetal bearing performance

The bimetal bushing has the advantages of good wear resistance. Especially suitable for medium speed medium load and low-speed high load and other occasions. Through special technology means, can be processed on the friction surface of a variety of oil groove, oil hole, and oil hole, so as to adapt to the use of different lubrication conditions. Products which have been widely used in an automotive engine, chassis, motorcycle clutch, gear pump scrubbing plate, and lifting equipment and other fields.
