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 .
1. PTFE with fibre 0.01~0.03mm
2. Stainless steel backing 0.7~2.3mm
Technical:
Load capacity: 100N/mm2 Temperature: -190°C ~+280°C
Speed limit: 2.5m/s Friction coef(µ): 0.03~0.18 PV
limit(dry): 3.0N/mm2 .m/s PV limit(oil): 40N/mm2 .m/s
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 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.
