2. It has the advantage of low wear,low friction and with long life.

3. Load will spread over a wider area due to the bearing material's elastic nature.

4. Low stick slip properties ensuring accuracy of machine operation under low silding speeds.

5. Low vibration,low noise and non-pollution in operation.

6. PTFE and Lead film is transferred to the mating shaft to improve running properties.

7. It can be used in low hardness of mating shaft,so the shafts processing is easy.
