The
IUDI-type piston rod seal is a high-performance single-acting dynamic sealing component tailored for reciprocating piston rod operation in hydraulic cylinder systems. Made of high-toughness wear-resistant polyurethane material, this IUDI rod seal features excellent pressure resistance, low friction and superior anti-aging performance, adapting to long-term cyclic operation and variable heavy-load working environments of engineering hydraulic equipment.
Adopting an optimized precision lip structure, the
IUDI-type piston rod seal creates uniform and stable contact pressure on the rod surface during reciprocating motion. It reliably prevents outward leakage of hydraulic fluid and avoids system pressure drop. The upgraded seal profile delivers strong anti-extrusion capacity against instantaneous pressure surges, effectively inhibits low-speed stick-slip phenomenon, and minimizes frictional heat accumulation during continuous high-frequency operation, with great compatibility with mainstream mineral-based hydraulic oils.
Designed to fit standard rod seal grooves, the
IUDI-type piston rod seal supports quick on-site installation and convenient spare part replacement. It is widely suitable for excavators, construction machinery, lifting devices, agricultural hydraulic facilities and various industrial hydraulic cylinders. Equipped with IUDI rod seals, hydraulic systems can effectively reduce component wear, lower leakage failure rate, cut maintenance costs and achieve longer service life of the overall sealing assembly.
