WB-010 is backed with copper-plated steel with porous bronze sintered on the steel and polymers imbedded into the bores of the bronze.The steel back provide the bush with stronger mechanic strength and poad capability.By combing the metals and the polymers together, its products are endowed with the lowerfriction coefficient and good capacity of anti-abrasion and self-lubrication.Moreover, the steel back is plated with a erosion-prevention layer.
