TCB100 is backed with copper-plated steel with porous bronze sintered on the steel and polymers (PTFE) 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 an erosion-prevention layer. Products of TCB 10 series are widely applied in printing, textile and tobacco machinery, gymnastic equipments, etc.
