Steel Brass 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.

 

Disruptive technological advantages

Bimetallic composite structure

High-strength steel backing

Wear-resistant copper alloy layer

Military-grade durability: Passed 2 million reciprocating tests, with a wear of less than 0.05mm

Intelligent lubrication design: Optional graphite inlay or PTFE composite lubrication system

Extreme working condition expert: Stable operation from -40℃ to +280℃

 

Six-dimensional performance comparison

Load-bearing capacity: 300% higher than pure copper bushings

Cost-effectiveness: It saves 35% of material costs compared with bronze integral casting

Thermal conductivity: The thermal conductivity coefficient reaches 60W/m·K

Installation convenience: Optimized interference fit design

Environmental friendliness: Lead-free formula is available as an option

Service life: 5 to 8 times longer than that of ordinary bushings
