SF-1 is wall wrapped bearings made
of triple layer composites material which consists
of a steel backing, a sintered porous 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 is needed. Moreover,
it is of low cost, low vibration and low noise,
compact and light. SF-1 is widely applied in various
sliding articles of different kind of machines such
as textile machines, tobacco machines, hydraulic
