Wear Resistant & Durable Graphite copper sleeve JDB 5*9*20 Rubber machinery bushing
This JDB5*9*20 self-lubricating bush was developed for oscillating joints that never complete a full rotation. In such motion the oil film of a plain bronze bush tends to collapse; the graphite inserts here keep replenishing a thin dry film, so wear stays even across the loaded arc.

Why the JDB5*9*20 bush fits Rubber machinery joints
- Self-lubricating graphite plugs reduce dependence on manual greasing
- Brass alloy matrix with high load capacity and good heat conduction
- Low and stable friction coefficient under boundary lubrication
- Resists seizure during start-stop and oscillating motion
- Ground bore and controlled wall thickness for a reliable press fit
- Suitable for dusty, wet and high-temperature working conditions
