Bimetal bushings and sleeves, specifically the 800 series and 72 model, are precision-engineered components made of a unique combination of materials to achieve optimal performance in various industrial applications. The key material in these components is a copper alloy known as CuSn4Pb24.
CuSn4Pb24 is a bronze alloy composed of copper, tin, and a small amount of lead. The composition of this alloy provides several key benefits:
Wear Resistance: The addition of tin and lead to copper results in an alloy that is highly resistant to wear. This makes it an excellent choice for bushings and sleeves, where continuous friction and abrasion are common.
Self-Lubricating: CuSn4Pb24 exhibits excellent self-lubricating properties, meaning it can lubricate itself under operating conditions, reducing the need for external lubricants. This further enhances its wear resistance and longevity.
Corrosion Resistance: The alloy is also resistant to corrosion, making it suitable for use in environments where exposure to moisture, chemicals, or other corrosive agents is possible.
The bimetal construction of these bushings and sleeves combines the wear resistance and self-lubricating properties of CuSn4Pb24 with the strength and rigidity of a steel backing. This results in a component that is both durable and reliable, able to withstand the rigors of continuous use in demanding industrial environments.
In summary, bimetal bushings and sleeves made from CuSn4Pb24 and steel offer an exceptional combination of wear resistance, self-lubrication, and corrosion resistance. These properties make them ideal for use in a wide range of applications, including but not limited to machinery, automotive components, and precision instruments.
depending on lubrication conditions. In some cases, a dry bearing can also be used under lubricated conditions.With our wide stock availability, daily updated on our website,https://www.viiplus.com we are able to satisfy promptly every customer’s needs.

The bimetal bushings product is based on high quality low carbon steel, with sintered lead-tin bronze alloy CuSn4Pb24 on the surface. The alloy surface can be processed into oil groove, which is convenient for oil storage and effectively reduces wear.The steel back can be plated with anticorrosive coating as required.This series of products are often used in internal combustion engine spindle and connecting rod bearings, thrust pads, rolling bearings and so on
The product is based on high quality low carbon steel and sintered lead tin bronze alloy CuSn10Pb10.The diamond hole is rolled on the surface of the alloy and filled with special solid lubricant to effectively reduce wear.The steel back can be plated with anticorrosive coating as required.It is suitable for high temperature, water solution infiltration or other occasions where oil cannot be added or where oil is difficult.
