Bimetal Flanged Bushing

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 value

Bimetallic composite structure: High-strength steel backing + wear-resistant copper alloy layer, with load-bearing capacity increased by 300%

Integrated flange design: Axial positioning accuracy ±0.02mm, impact resistance performance improved by 50%

Extreme working condition expert: Stable operation from -40℃ to +280℃ (instantaneous 350℃)

 

Five-dimensional performance advantages

Load-bearing capacity: 120% higher than that of integral cast copper bushings

Cost-effectiveness: Material costs are reduced by 35%, and lifespan is increased by 5 times

Easy installation: The interference fit tolerance is optimized to ±0.015mm

Maintenance-free: No lubricant needs to be added within the designed service life

Environmental protection and safety: Lead-free formula is available
