Bimetal Bushing BIM-720

Definition

Bimetal bushings are a kind of sliding bearing components made of two different metal materials composite, usually low carbon steel as the substrate, the surface sintered or composite copper alloys (such as CuPb10Sn10, CuPb24Sn4, etc.) in order to form a wear-resistant layer. The design combines the high strength of steel with the wear resistance and self-lubricating properties of copper alloys, which can withstand high loads and operate stably at low speeds or under limited lubrication conditions.

Core advantage

• Strong steel substrate support: mild steel as the substrate, providing a static load capacity of up to 150N/mm², excellent resistance to impact and deformation, suitable for heavy-duty machinery (e.g. mining equipment, construction vehicles).
• Reduced lubricant consumption: The self-lubricating feature reduces the use of grease by more than 50%, which is in line with environmental requirements.
• Easy replacement: modular design supports quick disassembly and reassembly, e.g. in heavy truck balance axles, replacement time is 70% shorter than conventional bushings.
• Self-lubrication is compatible with boundary lubrication: the copper alloy layer contains soft phases such as lead and tin, which can form a transfer film when lubrication is insufficient or when oil is supplied intermittently, avoiding the risk of shaft holding caused by dry friction.
