Graphite Impregnated Bronze Bushings

Graphite impregnated bronze bushings are also known as graphite plugged bronze bearings or oilless bronze bushings. Graphite impregnated bronze bushings are great for applications where maintenance is difficult and where normal grease and oil based lubricants can burn off due to high temperatures. Bronze body provides the necessary strength to the bearing and graphite plugs acts as reservoir of lubricants. Graphite film from the graphite plug is transferred onto the shaft as it rotates and acts as lubricant even under high loads and low speeds. The applications for these oilless bronze bushings include construction equipment, transportation machinery, mining equipment etc. Graphite impregnated bronze bushings are machined out of cast bronze and plugged with graphite plugs. These bearings are available in cylindrical, flanged cylindrical shapes and flat wear plates and machined to precision tolerances. Metalcomp specializes in the manufacture and export of customized graphite plugged bronze bushings for a diverse range of sizes and applications. We manufacture graphite plugged bronze bushings as per client’s drawings and specifications.
