HMEC DX bushing is a kind of marginal lubricating bushing. It is backed with copper-plated steel with porous bronze sintered on it and polymers (POM) imbeded into the bores of the bronze. The steel back provides the products with high quality low carbon steel. Oil dents stamped on the surface of the polymer can achieve good lubrication between the bushing and its mating axls. It is of good anti-abrassion and load capacity. The plating coating on the surface is erosion protective and it is enviromental protective as no lead included in the surface of polymer POM. Products of HMEC DX series bushings are widely used on automotive chassis, forging machines, mine quarrying machines, metal melting and casting machines and in water irrigating and steel rolling industries.
