IUIR Rod Seal – One-piece double-acting rod seal with integrated anti-extrusion rings and pressure-relief/bleed-back geometry. Asymmetric lip profile delivers positive bidirectional sealing while allowing controlled fluid return to the low-pressure side. Built-in backup rings prevent gap extrusion under high-pressure spikes and repetitive cyclic loading. Optimized contact geometry minimizes hydrodynamic pressure entrapment, reducing lip lift-off and ensuring stable sealing performance at elevated speeds. Cartridge-style monobloc construction reduces installation errors and lowers groove machining costs. Ideal for high-pressure, high-cycle hydraulic cylinders in mobile, industrial, and off-highway equipment. Material: abrasion-resistant polyurethane with integrated support elements. Temp: –35°C to +110°C. Pressure: up to 45 MPa. Speed: up to 2 m/s.
