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 seal, no interference on the ID or OD.
• For use as rod or piston seal
•  Preload effected through V-spring which ensures the continious pressure on

the sealing lips.

• Retainer nose on inside and outside lip.
•  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 160 bar, max. speed 5 m/s linear; 0,1m/s rotating.
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.
