Strict Quality Inspection Graphite copper sleeve JDB 5*7*8 Excavator bushing
Pressed into a worn housing, the JDB5*7*8 bush restores the original bore size and adds dry-running capability the original part never had. Its 5 mm bore is honed for shaft contact, while chamfered ends ease installation and protect the graphite inserts from shearing during the press fit.
