Bimetal Bushing
Overview
Bimetal bearings are engineered with a high-quality low-carbon steel backing sintered or rolled with surface layers such as lead-tin bronze or aluminum-tin alloys through multi-stage processing, and are widely produced in structural forms including bushings, plain bearings, and thrust washers—among which bushings are the most common. Commonly used alloy materials include CuPb10Sn10, CuPb24Sn4, CuPb30, CuSn6Zn6Pb3, and AlSn20Cu. In alignment with growing international environmental requirements, an eco-friendly material option, CuSn6.5P0.1, has been developed and is now extensively applied in the market.

Key Applications
FAQs
How are bimetal products lubricated?
Due to the material characteristics of bimetal bearings, they must operate in an oil-lubricated environment. Depending on the application, they are typically designed for three lubrication conditions:
Low-Speed Applications: Such as automotive balance bridges, leaf springs, brake pedals, steering knuckles, punch guide plates, and bulldozer support/idler wheels. These can be designed for grease lubrication—grease is applied during assembly and replenished periodically.
Medium-Speed Applications: Including connecting rods, punching and shearing machine shafts, and conveyor wheels. These are suitable for oil cup lubrication.
High-Speed Applications: Such as gearboxes, oil pumps, cylinders, engines, and clutches. These are designed for oil-immersion lubrication.
