PVB017 Brown PTFE Self-Lubricating Bushing with 140N/mm² Load Capacity and -195℃ to 280℃ Temperature Range
PVB017 Brown PTFE self-lubricating DU bearing features a steel back construction with specialized anti-wear layer and brown PTFE lining. Engineered specifically for vehicle seat adjustment mechanisms, this metal polymer composite bushing provides reliable performance without external lubrication.
- Brown PTFE surface layer for low friction
- Sintered bronze intermediate layer for wear resistance
- Steel backing for structural strength
- Copper or tin plating for corrosion protection
- Flexible rotation capabilities
- Small friction coefficient (0.04-0.20)
- Smooth operation with minimal noise
- Self-lubricating design eliminates maintenance
