Product Description

Wear Resistant & Durable Graphite copper sleeve JDB 4*8*8 Loader bushing

This JDB4*8*8 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.
