KDB-20 Boundary Lubricating Bushing

Structure Characteristics and Applications

KDB201 is designed for marginal lubricating bushing. It is backed with copper-plated steel with porous bronze sintered on it and polymers (POM) imbedded 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 axis. It is of good anti-abrasion and load capalility. The plating coating on the surface is erosion protective. And it is environmental protective as no lead included in the surface polymer POM. Products of KDB201 series are widely used on automotive chassis, forging machines, mine quarrying machines, metal melting and casting machines and in water irrigating and steel rolling industries.
