Description
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, combined with pressure ring and
support ring.
- By adjusting the number of packings friction and leakage characteristics can be
influenced.
- Excellent static and dynamic sealing performance.
- Excellent performance in high pressure conditions.
- Useable for short and long stroke lengths.
- High wear resistance.
Application
Reciprocating pistons/rods in hydraulic cylinders, plungers etc.
Used in heavy duty applications (presses) with return stroke by equipment weight.
Max. pressure 500 bar, max. speed 0.5 m/s.
Installation
Installation normally in open housings.
At closed housings the parts need to be split. In this case the seal must be done slightly
larger (approx. 1% in diameter)
