Rod Seals

Features

• Asymmetrical, single acting rod seal, designed with interference on the OD 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 rods 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.

Features

• Asymmetrical, single acting rod seal, designed with interference on the OD which provides a good static fit in the groove.
• 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

Reciprocation rods in hydraulic cylinders, plungers.

Universal rod seal for larger extrusion gaps and higher load impacts.

Max. pressure 700 bar, max. speed 0.5 m/s, depending on material selection.

Application

Reciprocation rods in hydraulic cylinders, plungers.

Universal rod seal for small extrusion gaps and minor load impacts.

Also used as secondary seal in combination with RS09 (PTFE + O-Ring energizer). Max. pressure 400 bar, max. speed 0.5 m/s.
