Low Noise Graphite copper sleeve JDB 4*6*10 Pump truck bushing

Low Noise Graphite copper sleeve JDB 4*6*10 Pump truck bushing

Every JDB4*6*10 sleeve starts as a centrifugally cast brass tube, is machined to a 4 mm bore and 10 mm length, then drilled to accept graphite columns at a controlled density. The result is a maintenance-free sliding bearing that combines the load capacity of bronze with the dry-running behaviour of graphite.

Why the JDB4*6*10 bush fits Pump truck 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 Pump truck fleets

Ordering information

If your Pump truck 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.
