JYB*1
is backed with copper-plated steel with porous bronze sintered on
the steel and polymess(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 JYB*1
series are widely applied in printing, weaving and tobacco
producing machines, gymnastic equipments, etc.
