Long Service Life Graphite copper sleeve JDB 5*8*15 Excavator bushing

Long Service Life Graphite copper sleeve JDB 5*8*15 Excavator bushing

The JDB5*8*15 graphite copper sleeve is turned from high-lead brass and fitted with graphite plugs covering roughly a quarter of the sliding surface. This ratio is enough to keep friction low under boundary lubrication without weakening the bronze matrix that carries the shock loads typical of Excavator.

Why the JDB5*8*15 bush fits Excavator joints

• Solid lubricant works from -40 C to 300 C without re-greasing
• Reduced friction heat protects seals and shaft surfaces
• High compressive strength for slow, heavily loaded rotation
• Graphite plugs countersunk to survive assembly and handling
• Consistent batch quality from CNC machining and inspection
• Cuts downtime and spare-part cost on Excavator fleets

Ordering information

If your Excavator uses a similar pivot but with different dimensions, the same brass-graphite construction can be made to your specification, including non-standard bore, wall thickness and graphite density.
