1. PTFE with oil fibre can protect the shaft, while machine in operation.
2. It is of low friction coefficient, good anti-wear.
3. Good running in property.
4. It fits well in motion of circumgyration, sway and to-and-fro.
5. Good anti-corrosion.
6. It can be used in food machine, pharmaceutical etc, due to lead-free.
7. It is mainly used in the condition of strong acid and alkali, such as chemical Industry, pumps, valves etc.

Dry bearing is a new type of lubrication bearing, which has the characteristics of metal bearing and oil-free bearing. It has metal matrix loading and special solid lubricating material lubrication. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and strong self-lubricating ability. We are provide dry bearings, self lubricating bearing, wrapped bronze bearing, bimetallic bushings, steel bronze bushings.
