Sep 03, 2016

① a certain degree of flexibility. Clamping force can produce a certain amount of radial forces and close contact with the shaft.

② has enough chemical stability. Do not pollute the media, packing do not swell by media, packed in the impregnating agent is not medium, sealing surface of the packing itself does not corrode.

③ good self-lubricating properties. Wear resistance, low coefficient of friction.

About shaft a few eccentric, packing should have enough floating elastic.

⑤ made easy, convenient loading.
