Lining-Sprayed Self Lubricating Bushing Marine Stainless Steel Bush SF-1DU for Valves
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 .

|Type||In Air||In Vacuum||In water||In Vapor||Weak Acid||middle Acid||Strong Acid||In Alkali|
1. PTFE with oil fiber 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.
Friction & Wear Test:
1. Anti-rust oil + plastic films or bag + carton and pallet
