We are a leading supplier of bimetal bearing bushes made from a combination of steel and AISn20Cu alloy. Our products are renowned for their high quality and durability, making them ideal for a wide range of industrial applications.
The use of steel as the base material ensures excellent strength and rigidity, while the AISn20Cu alloy provides exceptional wear resistance and self-lubricating properties. This unique combination of materials results in a bearing bush that can withstand high loads and speeds while maintaining smooth and efficient operation.
To further enhance the performance of our bearing bushes, we offer both copper plating and tin plating options. Copper plating improves conductivity and corrosion resistance, while tin plating enhances wear resistance and lubricity. These plating options can be customized to meet the specific requirements of your application.
As a China-based supplier, we pride ourselves on providing high-quality products at competitive prices. We adhere to strict quality control standards and use only the finest materials in our manufacturing process. This ensures that our bearing bushes meet the highest standards of performance and reliability.
Whether you need bearing bushes for pumps, motors, compressors, or any other rotating equipment, we have the solution for you. Contact us today to discuss your requirements and learn more about our bimetal bearing bushes.
VIIPLUS is a professional supplier of self - lubricating bearings, providing the world with high quality self - lubricating products.
Bimetal bearing is made of steel sintered with CuPb10Sn10 or CuSn6Zn6Pb3 as a lining layer.This type of bushing show its best performance among bushings made of Cu-lead alloy material in this product range.It suits most for middle speed and high impact conditions.Its application including balance suspensions of heavy-duty trucks, track roller of bulldozers,auto chassis etc.

1. It is a steel and copper alloy product with low carbon steel plate as the matrix material and surface sintered CuPb10Sn10 or CuSn6Zn6Pb3 material. The product is a kind of balance bridge bushing and gasket for heavy duty vehicles with the strongest bearing capacity among the double alloy bearings.The slave wheel of a bulldozer;Automotive steel bushing, all used in this product. It is a widely used high - load low - speed sliding bearing.
2. The product is made of CuPb24Sn4 alloy sintered on the surface of a steel plate.The product has good anti-fatigue strength and bearing capacity.Suitable for medium speed medium load.There are occasions for oil sliding.When the surface is plated with soft alloy, it can be used as bearing and connecting rod bushing for high speed internal combustion engine to achieve good wear resistance and fatigue resistance.
3. The product is made of CuPb30 material sintered on the surface with steel plate as the matrix.Due to the high lead content, the product has good bite resistance and foreign body embedding.If the working surface is plated with soft alloy material, it can be used as high speed, medium and low load internal combustion engine spindle, connecting rod bushing, rocker arm bushing;Oil mercury side friction sheet.
4. Lead-free bimetal bearing, is an environmentally friendly bimetal bearing, it is based on low carbon steel plate as the matrix, the surface of the sintered CuSn6.5P0.1 steel copper alloy products.The product has high fatigue strength and bearing capacity, good sliding performance, in many cases can replace the lead bimetal bearing or copper sleeve.
