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.

Installation

Snap-in installation.
