Wrapped Stainless Steel Bushing

Multi-layered:
1. Support Base: Stainless Steel
2. Intermediate Layer: Bronze Powder
3. Inner Sliding Layer: PTFE

SF-1SW is of oil resistant,acid resistant,alkaliresistant and seawater resistant.more over,there is no lead in the PTFE surface layer and so is particularly fit for bushings in food stuff machines,alkali flow meters,pumps motion elements in pharmaceutical machines,printing machines chemical engineering machines and other ocean industry.this is a triple layers composites bush,the base material being a bronze plate and a film of heat resistant power filled PTFE being calendered onto the sintered spherical bronze interlayer.

Wrapped Stainless Steel Bushing Materials Structure

1.PTFE mixture 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming an oxide type solid lubricant film.
2.Sintered bronze powder 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE-lead mixture.
3.Steel backing, gives exceptionally high load carrying capacity, excellent heat dissipation. Have very good corrosion resistance.

Wrapped Stainless Steel Oilless Bushing Features

PTFE with oil fibre can protect the shaft,while machine in operation.
It is of low friction coefficient,good anti-wear.
Good running in property.
It fits well in motion of circumrotation,sway and to-and-fro.
Good anti-corrosion.
It can be used in food machine, pharmaceutical machine etc.due to lead-free.
It is mainly used in the condition of strong acid and alkali, such as chemical industry,pumps,valves etc.
