Precious Machined Graphite copper sleeve JDB 6*8*12 Port machinery bushing

Dimensional accuracy matters more than raw hardness in a pivot bush, and the JDB6*8*12 sleeve is finished on CNC centres to hold bore roundness and length tolerance tightly. Graphite columns are set at an angle that follows the main load direction of Port machinery joints.
