Coeff.of linear expansion
1. It may be used where no oil can be applied or oil is difficult
to be applied.
2. It has the advantage of low wear,low friction and with long
3. Load will spread over a wider area due to the bearing material's
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
7. It can be used in low hardness of mating shaft,so the shafts
processing is easy.
8. The machine will be compact because of the thin thickness and low
weight of the bush.
9. Electro plating is plssible to prevent corrosion.
