IUIS type piston rod seal is a single-acting reciprocating hydraulic rod seal specially designed for hydraulic cylinder piston rods. It adopts a precision asymmetrical lip structure with pressure self-energizing sealing principle. As hydraulic pressure builds up, the sealing lip closely fits the rod surface to block medium leakage and prevent external dust, dirt and moisture from entering the cylinder.
Made of premium polyurethane material, the IUIS piston rod seal features excellent wear resistance, high tear strength and low friction coefficient. Its optimized cross-section delivers strong anti-extrusion performance under high working pressure, avoiding extrusion failure during long reciprocating movement. It can operate stably under pressure up to 35 MPa, with working temperature ranging from -30℃ to 100℃.
Compatible with mineral hydraulic oil and most conventional hydraulic fluids, IUIS hydraulic rod seals are widely used in excavators, forklifts, injection molding machines and other industrial hydraulic equipment. It fits standard seal groove sizes for simple installation and direct replacement. Reducing oil leakage trouble and cutting maintenance costs, IUIS piston rod seal offers a dependable dynamic sealing option for heavy-duty hydraulic systems.
