1.PTFE with fibre 0.01~0.03mm
2.Stainless steel backing 0.7~2.3mm |
| Introduction |
| SF-1SS stainless bushing with plastic coated is based on stainless steel spay-painted PTFE on the surface.It is of anti-acid,anti-alkali,anti-salty liquid and can be widely used in chemical industry such as acid/alkali flow indicator,pumps,valves etc and also in the sliding position where anticorrosion is a necessity mostly in sea industry |

| Application |
1.PTFE with oil fibre can protect the shaft, while machine operated.
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 medium acid and alkali, such as chemical industry,pumps, |
