SF-1S Stainless Steel Bush |
Metallurgical structure |
|
|
1.PTFE with lead 0.01~0.03mm
2.Porous bronze 0.2~0.3mm
3.Steel backing 0.7~2.3mm
|
Introduction: |
SF-1S 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.

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