Bimetal 800 Split Type Bimetal Bearing Bushes are a unique and versatile solution for bearing applications. These bushings feature a bimetallic construction, combining the benefits of two different metals to create a high-performance bearing component.
The split type design allows for easy installation and removal, making maintenance and replacement a breeze. The bimetallic material used in these bushings typically consists of a softer, more wear-resistant metal on the sliding surface, such as copper or bronze, and a harder, more durable metal as the backing, often steel.
The steel-backed solid sleeve bushing provides excellent support and structural integrity, ensuring the bushing can withstand high loads and frequent friction. The buckle design, if present, further enhances the bushing's stability and prevents it from slipping or moving out of position during operation.
Overall, Bimetal 800 Split Type Bimetal Bearing Bushes offer a reliable and long-lasting bearing solution that is suitable for a wide range of applications, including heavy-duty machinery, automotive components, and industrial equipment.

The bimetal bearings is made of high quality low carbon steel with the surface of sintered lead-tin bronze alloy CuSn10Pb10. The surface of the alloy can be processed into oil groove to facilitate oil storage and effectively reduce wear.The steel back can be plated with anti-corrosion coating as required.This series of products are often used in internal combustion engine spindle and connecting rod bearing, thrust gasket, roll bearing and so on.
