IUIS Rod Seal – High-Pressure Double-Acting Hydraulic Rod Seal with Integrated Backup Rings and Bleed-Back Function
High-performance IUIS rod seal for high-pressure hydraulic cylinders. Double-acting, anti-extrusion, with integrated backup rings and bleed-back geometry. PU, –35°C~110°C, ≤45 MPa.
IUIS Rod Seal – A premium hydraulic rod seal engineered for high-pressure, high-cycle double-acting cylinder applications. This one-piece cartridge seal features integrated anti-extrusion backup rings and a precision-engineered bleed-back/relief lip geometry that enables controlled fluid return while maintaining positive bidirectional sealing. The asymmetric lip profile ensures reliable sealing performance under pressure spikes and cyclic loading, while the low-friction polyurethane compound minimizes heat generation and extends service life. The compact monobloc design simplifies installation, eliminates assembly errors, and reduces groove machining costs — making it an ideal sealing solution for mobile and industrial hydraulic cylinders operating under extreme conditions. 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.
