Function
Symmetrical piston/rod seals are designed to seal the pressurized hydraulic fluid against
the atmosphere or between two pressurized spaces.
Features
- Symmetrical, single acting piston/rod seal, no interference on the ID or OD.
- Preload effected through round Helicoil-spring which ensures high pressure on
the sealing edges.
- Excellent static and dynamic sealing performance.
- Excellent sealing performance in low and high pressure ranges.
- Useable for short and long stroke lengths.
- Low friction in dry running or poor lubrication conditions.
- Negligible tendency to “stick-slip” effect, small break away loads.
Application
Reciprocating and swivelling pistons in hydraulic cylinders, plungers.
Chemical and pharmaceutical industry, aggressive fluids and high temp.
Max. pressure 200 bar, max. speed 1 m/s
Installation
Installation in open housing, snap-in installation possible in special designed housings.
We recommend to maintain a nominal width/seal height ration (CS/NH) above 1/1,5.
