Bimetal Bearing 720 is a high-performance bearing component that utilizes bimetallic technology to enhance its durability and wear resistance. The bearing bushes are made from CuPb30 material, a type of lead bronze alloy that exhibits excellent mechanical properties and sliding characteristics.
The bimetallic construction of these bearings combines the advantages of two different metals, providing a strong and wear-resistant surface for the sliding action. The CuPb30 material, specifically, offers high hardness and good fatigue resistance, making it suitable for high-load and high-speed applications.
The flanged sleeve design of these bearings adds extra stability and support, preventing any slippage or misalignment during operation. This ensures smooth and reliable performance, even under extreme conditions.
Overall, Bimetal Bearing 720 with CuPb30 material and flanged sleeve design offers a robust and long-lasting bearing solution for various industrial and mechanical applications. Wh it's used in heavy machinery, automotive parts, or other critical equipment, it provides reliable performance and extended service life.
Lead Bronze Bimetallic Bearings Made To Order From China.Steel+CuPb30 Bimetal Bearing Manufacturer,Sliding layer can be machined with lubricating grooves and/or with grease indents.In addition to the standard products shown in the catalog, you can also provide non-standard products or order according to customer requirements.
bi-metal bushing is backing on low carbon steel, sintered with CuPb30 bronze powder. It has good performance in shaft seizing resistance and cover up alien substance due to the high lead content.
When soft alloy is plated on the bushing surface, it can be applied under high speed and middle load working situation, just like engine main bearing, connect-rod bushing, rocket arm bushing and oil pump side plate.
Liner material: CuPb30
Load capacity: 25N/mm2
Temperature Max: 170℃
Liner hardness: HB30~45
ZCuPb30 casting copper alloy has good self-lubrication, free cutting, poor casting performance, easy to produce specific gravity segregation.ZCuPb30 casting copper alloy for high slip speed requirements of bimetallic bearing, grinding parts, etc.
High lead content may cause pollution to the environment, please use in the correct environment
