Symmetrical piston/rod seals are designed to seal the pressurized hydraulic fluid against
the atmosphere or between two pressurized spaces.

Symmetrical, single acting piston/rod seal, no interference on the ID or OD.
Preload effected through Helicoil-spring which ensures high pressure on
the rounded sealing lips..
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.
Also used for gas applications.
Negligible tendency to “stick-slip” effect, small break away loads.

Reciprocating and swivelling pistons in hydraulic cylinders, plungers.
Chemical and pharmaceutical industry, aggressive fluids and high temp.
Max. pressure 160 bar, max. speed 5 m/s linear; 0,1m/s rotating.

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.
