Description
Function
Piston seals are designed to seal the pressurized hydraulic fluid against the atmosphere or between two pressurized spaces.
Features
- Asymmetrical, single acting piston seal, designed with interference on the ID which provides a good static fit in the groove.
- Dynamic sealing lip shorter than static lip to avoid drag pressure.
- Sharp lips on ID and OD.
- Good static and dynamic sealing performance.
- Good performance in low pressure conditions.
- Useable for long stroke lengths.
- Out-of date profile; only used in old machineries.
- Poor sealing that causes a relative thick oil film.
Application
Reciprocating pistons in hydraulic cylinders, plungers etc.
Max. pressure 400 bar, max. speed 0.5 m/s.
Installation
Snap-in installation.
