Product Overview

Description

self lubricating bushing

 

  SF-1 is wall wrapped bushing made of triple layer composites material which be consisted of a steel backing a sintered prrous bronze particles interlayer and calendared with PTFE and Pb mixture as surface layer. It is of low friction coefficient, anti-wear , anti-corrosion and can be used without oil, or only a trace of oil if needed. Moreover, it is of low cost, low vibration and low noise, compacted and light, SF-1 is widely applied in various sliding articles of different kind of machines, such as textile machines, tobacco machinese, hydraulic vechicles, automobiles, agriculture and forests machinese and so on.
