Description

Long Service Life Graphite copper sleeve JDB 4*8*22 Port machinery bushing

The JDB4*8*22 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 Port machinery.
