SS Bronze Powder + PTFE Self Lubricating Bearings Multilayer Composite
It is backed with stainless steel with porous bronze sintered on it and polymers imbedded into the bores of the bronze. The stainless steel back provides the bush with stronger mechanic strength and load capability. By combining the metals and the polymers together, the products are endowed with the lower friction coefficient and good capacity of anti-abrasion and self-lubrication. Moreover, the stainless steel back can be effectively preventing chemical erosion. This series are widely applied in printing and dyeing machines, and machines used in the ocean industry, etc.

Physical and Mechanical Performance
Normally, the surface polymer is chemical-erosion resistant quality. However it can be eroded by fused alkali metal and high temperature fluorine compounds. Stainless steel back is also chemical erosion preventive.
