Piston Seals

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.
• Increased preload due to an additional O-Ring.
• Activated back-up ring prevents and reduces gap extrusion.
• Excellent static and dynamic sealing performance.
• Excellent performance in all pressure ranges.
• Used for short, pulsating strokes.
• No reverse leakage when changing direction
• Recommended for positioning or holding under pressure.

Application

Reciprocating pistons in hydraulic cylinders, plungers, push rods, fittings, etc. Switching or clamping functions

Max. pressure 700 bar, max. speed 0.5 m/s.

Installation

Snap-in installation.

Application

Reciprocating pistons in hydraulic cylinders, plungers, push rods, fittings, etc. Switching or clamping functions.

Max. pressure 400 bar, max. speed 0.5 m/s.

Installation

Features

• Asymmetrical, single acting piston seal, designed with interference on the ID which provides a good static fit in the groov
• Dynamic sealing lip shorter than static lip to avoid drag pressure.
• Excellent static and dynamic sealing performance.
• Useable for long stroke lengths.
• Negligible tendency to “stick-slip” effect above a speed of 0.15 m/s.
• For lower speeds the dynamic lip should be redesigned (shorter, stiffer).
• Activated back-up rings prevent and reduce gap extrusion.

Application

Reciprocating pistons in hydraulic cylinders, plungers.

Universal piston seal for small extrusion gaps and minor load impacts. Max. pressure 700 bar, max. speed 0.5 m/s.

Function
Piston seals are designed to seal the pressurized hydraulic fluid against the atmosphere or between two pressurized spaces.
