Wrapped Bronze Bushings

1. Product Definition & Manufacturing

Wrapped bronze bushings are precision-engineered sliding bearings formed by cold-rolling high-density copper alloy strips (typically CuSn8 or CuSn6) into cylindrical shapes with overlapping seams. Key manufacturing features include:

Material composition: 90-92% copper + 8-10% tin for optimal strength/lubricity balance

Surface treatments: Optional PTFE coating or oil-impregnation for self-lubrication

Dimensional standards: Compliance with ISO3547 for agricultural/forestry machinery

2. Performance Advantages

Load Capacity: 50-120N/mm² static load rating, superior to sintered bronze bushings

Wear Resistance: 0.05-0.15mm/1000h wear rate in dry conditions

Temperature Range: -30°C to +180°C operational stability

3. Industrial Applications

4. Market Trends (2025)

Price range: $0.10-$50/piece depending on size and coating

Emerging demand: Electric vehicle suspension systems requiring lightweight CuSn8 variants

Innovation focus: Laser-welded seams replacing traditional mechanical locking
