RDI Rotary Seal - inside sealing - OI Rotary Seals
1.Name: OI
Categories: Rotary Seals->OI
Pressure(MPa):30
Temperature (C): -35/+200
Speed(m/s):0.5
2. Standard Materials
Seal ring: filled PTFE
Back-up ring: POM or PA
O-Ring: NBR
3．Application Range
A filled PTFE seal ring, an energised O-Ring and two back-up rings compact seal. Special seal surface design to suit for high pressure and low viscosity. Concave back face design increases contact surface, prevents the seal ring rotating with the rod and shaft. Applied to engineering machinery, construction machinery and automobile machinery, ect.
Design and apply according to the standard of Hunger RDI series.
4．Characteristics
1- low coefficient of friction
2- can be applied to occasions where rod or piston sealing are required
3- no crawling and no stick-slip behavior
4- anti-wear property and dimension stability
5- simple groove and small sizes
6- lubricating cavity available2- for reciprocated and rotary sealing
