NMY Rod Seal – Asymmetrical Pressure-Balanced Rod Seal

NMY Rod Seal – Double-Acting Hydraulic Rod Seal with Asymmetrical Lips and Integrated Pressure Balance

NMY double-acting rod seal with asymmetrical lips and pressure balance for medium-pressure hydraulics. Low friction, compact, reliable. PU, –35°C~100°C, ≤35 MPa.

NMY Rod Seal – A precision-engineered double-acting hydraulic rod seal designed for medium-duty cylinder applications requiring reliable bidirectional sealing and pressure stability. This asymmetrical lip seal features an optimized lip profile that delivers positive sealing under both dynamic stroking and static dwell conditions, while the integrated pressure-relief geometry minimizes lip lift-off at elevated speeds and reduces hydrodynamic pressure entrapment. The low-friction compound reduces heat generation, stick-slip, and wear, extending service life in high-cycle operations. The compact cross-section simplifies groove machining and installation, making this medium-pressure rod seal ideal for mobile equipment, industrial machinery, and pneumatic systems where space and performance are critical. Material: premium polyurethane. Temp: –35°C to +100°C. Pressure: up to 35 MPa. Speed: up to 2.5 m/s.
