Material Features：

SF-1SS stainless steel 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 Feature：

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.
