High Precision PTFE Lip Rotary Shaft NBR Oil Seal Shore A85 With
Long Working Life
We are supplying professional oil seals with various types and
automotives/tractor /truck/ trailer oil seals. Custom oil seals can
be made with customs' request. Oil seal consists of three parts:
the seal body, strengthen the skeleton and the self-tightening
spiral springs.The role of oil seal of the transmission components
in general is in need lubrication components and parts output
isolation, and typically used for rotating shaft is a rotary shaft
lip seal. It can be divided in the seal, the outer seal, the inner
and outer exposed skeleton oil seal.
Properties of Different Rubber Materials
- Working temperature: -40℃~120℃
- Performance: Upgrade on the basis of the performance of cyanide
rubber, with higher working Temperature, better wear resistance,
alkali resistance, acid resistance, ozone resistance, Weather
