The
IUIR-type piston rod seal is a professional single-acting dynamic sealing element developed for reciprocating piston rod motion in hydraulic cylinder systems. Adopting high-toughness polyurethane raw materials with enhanced anti-aging and wear-resistant formulas, this IUIR rod seal provides stable sealing performance, outstanding pressure resistance and low-friction characteristics for long-cycle hydraulic operation under heavy-load working conditions.
Optimized with a precise sealing lip design, the
IUIR-type piston rod seal forms uniform fitting pressure on the piston rod surface during reciprocating movement. It effectively blocks outward hydraulic fluid leakage and prevents system pressure loss. The improved structural profile resists extrusion deformation under instantaneous pressure surges, suppresses stick-slip at low speed, and reduces frictional heat accumulation during continuous operation. It maintains excellent compatibility with conventional mineral hydraulic oils for engineering machinery.
Matching standard rod seal groove specifications, the IUIR-type piston rod seal allows fast installation and direct replacement without complex processing. It is widely applicable to excavators, construction machinery, lifting equipment, agricultural hydraulics and industrial hydraulic cylinders. Equipped with
IUIR rod seals, hydraulic systems achieve lower leakage rates, reduced component abrasion, less maintenance downtime and extended overall sealing service life.
