Specifications
Oil free telfon bushing SF-1 4020:low friction coefficient
good corrosion resistance
self-lubrating
low noise
SF-1 is a kind of oilless slide Bushing made of the PTFE composite material,Which is a copper-plateed 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.
