Lining-Sprayed Self Lubricating Bushing Marine Stainless Steel Bush SF-1DU for Valves
Description:
SF-1SS bushing is based on stainless steel back and spay-painted PTFE on the surface.It has good performance 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 anti-corrosion is a necessity mostly in marine industry .

SF 1SS CHEMICAL CHARACTERISTIC:
| Type | In Air | In Vacuum | In water | In Vapor | Weak Acid | middle Acid | Strong Acid | In Alkali |
| SF 1SS | OK | OK | OK | OK | OK | NO | NO | OK |
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, valves etc.
