Application characteristics
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 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.
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.It is widely used in
various sliding motions of defferent kind of machines such as
textile machine,tobacco machines,hydraulic vehicles Automobiles,agriculture
machines and so on.
