HBYR type piston rod seal is a single-acting reciprocating hydraulic rod seal customized for hydraulic cylinder piston rods. It adopts a well-designed asymmetrical lip profile with pressure self-energizing sealing principle. As hydraulic pressure increases, the sealing lip closely fits the rod surface to block internal hydraulic fluid leakage and prevent external dust, dirt and moisture from getting into the cylinder interior.
Produced from premium polyurethane raw material, the HBYR piston rod seal features excellent wear resistance, great tear strength and low friction coefficient. Its optimized cross-section structure provides reliable anti-extrusion performance under high pressure, preventing extrusion damage during long-term reciprocating movement. It can keep stable sealing performance at working pressure up to 35 MPa, with operating temperature ranging from -30℃ to 100℃.
Compatible with mineral hydraulic oil and most common hydraulic media, HBYR hydraulic rod seals are widely applied in excavators, forklifts, injection molding machines and other industrial hydraulic cylinders. It fits standard seal groove sizes for simple installation and direct replacement. With low leakage rate and extended service life, HBYR piston rod seal offers a trustworthy and cost-effective dynamic sealing solution for heavy-duty hydraulic systems.
