KDB-106 Self-Lubricating Multilayer Composite Bushing

Structure Characteristics and Applications

KDB10 is backed with copper-plated steel with porous bronze sintered on the steel and polymes (PTFE+Pb) imbedded into the bores of the bronze. By combining the metals and the polymers together, its products are endowed with the lower friction coefficient and good capacity of anti-abrasion and self-lubrication. Moreover, the steel back is plated with a erosion-prevention layer. Products of KDB 100 series are widely applied in printing, weaving and tobacco producing machines, gymnastic equipments, etc.
