Gymnastic Equipment 250N/Mm² Self Lubricating Bronze Bushings
It is backed with low-carbon steel with porous bronze sintered on the steel and polymers imbedded into the bores of the bronze. The 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, it is a lead-free and environment protection product. This series are widely applied in printing, weaving and tobacco producing machines, gymnastic equipment, shock absorbers, 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. Therefore its erosion-prevention quality is primarily decided by the quality of the steel back and its plating layer. Air-erosion could be effectively prevented if the steel back is bronze or tin-plated. If the bush is to be used in corrosive environment, the steel back needs to be plated with lead, zinc, nickel or nickel-chrome ally, etc.
Application
printing, weaving and tobacco producing machines, gymnastic equipment, shock absorbers, etc.
