OEM Standard Production Graphite copper sleeve JDB 6*8*15 Excavator bushing

OEM Standard Production Graphite copper sleeve JDB 6*8*15 Excavator bushing

A brass-graphite composite construction gives the JDB6*8*15 bushing two working modes in one part: it runs dry during start-up and short cycles, and it accepts grease where a lubrication point already exists. That flexibility keeps spare-part stock simple for workshops servicing mixed fleets.

• 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
