SF-1/SF-2
SF-1 is a kind of oilless Slide Bushing made of the Polytetrafluoroethylene (PTFE) composite material,Which is a copper-plated steel plate on to which a porous layer of tin bronze powder is sintered and also a mixture of PTFE and lead are filled into and covered the porous layer by a rolling process.
SF-2 is a boundary lubricating bushes made of the POM composite material, which also has a copper-plated steel plate on to which a tin bronze powder is sintered, modified polyformadehyde resin(POM) is firmly anchored in the sintered bronze layer. The surface of covering layer has many pockets to retain lubricating grease.
Structure：
steel backing,sintered porous bronze interlayer,PTFE with lead mixturer outside.
Property and application：
work in dry or a trace of grease,shaft grapping free,low friction and vibration, wear resistance, anti corrosion,noise aborber with compact structure. widely applied in various sliding motions of auto parts,textile and printing machinery.
Structure：
Steel based,porous bronze powder as interlayer,overlaid POMmaterial on the surface oil retainning groove.
Property and application：
normal work under oiless condition, anti-wear with low cost,popular in high load but low speed movement with frequent stop-start motion, Applied in auto classis forging machine,metallurgical ,civil, engineering, power station,station, strip,rolling industries etc.
