Price:
Negotiable
Product Description
Product Overview
PVB034 steel back bimetal bearing features AlSn20Cu tin aluminum alloy sintered onto low carbon steel backing. This construction provides excellent oil corrosion resistance, smooth surface operation, and outstanding embeddability with anti-seizure performance. Compliant with ROHS regulation 2000/53/EC.
Material Structure
- Sintered Tin Aluminum Alloy AlSn20Cu: 0.2-0.5mm thickness providing excellent self-lubricating properties
- Steel Backing: Provides mechanical strength and structural integrity
Performance Characteristics
- Medium fatigue-resistance with excellent load capacity
- Superior corrosion resistance and smooth sliding surface properties
- Good embeddability and anti-seizure performance
- Ideal for mating with soft shafts
