JDB ,cast bronze use high grade metal alloys as their base material and have finely finished surface with holes in which a specially formulated solid lubricant is embedded. The Lubricant cover up to 25-30% of the working surface. During operation the lubricant film is deposited automatically over the complete moving surface.

These Graphite bushings are widely applied in many positions. Just as casting machinery, ships, hydraulic turbines, injection molding machinery, tool machinery, light industries and so on. These bushings are very good at saving cost material. We can make all sizes and types, also by clients requests.
