SF-1S Stainless Steel Bush

Introduction:

SF 1S is of oil resistant,acid resistant,alkali resistant 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.

Technical:

Load capacity:140N/mm2 
Temperature:-195~+280°C 
Speed limit:2.5m/s 
Friction coef(u):0.04~0.20 
PV LIMIT(Dry):3.6N/mm2 .m/s 
PV LIMIT(Oil):50N/mm2 .m/s

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.
