Description

PTFE Metric Sleeve Bearings / Self Lubricating Bronze Bushings

It is backed with tin-bronze with porous bronze sintered on it and polymers imbedded into the bores of the bronze. The tin-bronze 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 tin-bronze back is good heat conducting capability. This series are widely applied in metallurgy machine and casting machines, consecutive casting machines, cemetery machines, spiral transporting machines, 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. But tin-bronze back can prevent air-erosion.
