steel backed sliding bearing:
WZB SF 1 is a kind of thin wall wrapped bearings made of tripple layer composites material
which consists of a steel backing, a sintered porous bronze particles interlayer and calendered
with PTFE and Pb mixture as surface layer.
This is of low friction coefficient, antiwear, anticorrosion and can be used without oil, or only a trace of
oil is needed. Moreover, it is of low cost, low vibration and low voice, compact and light, and can
form a transfer film of PTFE which protects the mating surface from scorring.
sf-1 is widely applied in various sliding articles of different kind of machines, such as
printting machines, textile machines, tobaccomachines, gymnastic machines, hydraulic vehicles,
automobiles, motorcycles, agriculture and forests machines and so on..
