OEM Standard Production Graphite copper sleeve JDB 4*8*12 Rubber machinery bushing

A brass-graphite composite construction gives the JDB4*8*12 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.

Why the JDB4*8*12 bush fits Rubber machinery 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 Rubber machinery fleets

Ordering information

If your Rubber machinery 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.
