Low Noise Graphite copper sleeve JDB 5*7*15 Crane bushing

Low Noise Graphite copper sleeve JDB 5*7*15 Crane bushing

Every JDB5*7*15 sleeve starts as a centrifugally cast brass tube, is machined to a 5 mm bore and 15 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.
