PSD Rod Seal – Pressure-Activated Double-Acting Rod Seal

PSD Rod Seal – Double-Acting Hydraulic Rod Seal with Pressure-Activated Lips for High-Pressure Cylinders.

PSD double-acting rod seal with pressure-activated lips for high-pressure hydraulic cylinders. Low friction, compact, reliable. PU, –35°C~110°C, ≤40 MPa, ≤2.5 m/s.

PSD Rod Seal – A high-performance hydraulic rod seal engineered for double-acting cylinder applications requiring reliable bidirectional sealing and pressure-activated performance. This double-acting rod seal features an asymmetric lip geometry that delivers positive sealing in both stroke directions with minimal leakage. The pressure-energized lip design ensures tighter sealing as system pressure increases, while the optimized lip contact reduces friction, wear, and heat buildup for extended service life. The compact cross-section allows space-saving groove design while maintaining seal stability under high-pressure conditions. This high-pressure rod seal is ideal for mobile equipment, industrial machinery, and hydraulic cylinders in medium to high-pressure systems. Material: abrasion-resistant polyurethane. Temp: –35°C to +110°C. Pressure: up to 40 MPa. Speed: up to 2.5 m/s.
