HBR type piston rod seal is a single-acting reciprocating hydraulic rod seal developed for hydraulic cylinder piston rods. It adopts a refined asymmetrical lip profile with pressure self-energizing sealing mechanism. When hydraulic pressure rises, the sealing lip tightly adheres to the rod surface to stop internal fluid leakage and prevent external dust, debris and moisture from infiltrating into the cylinder.
Manufactured from high-performance polyurethane material, the HBR piston rod seal has outstanding wear resistance, superior tear resistance and low friction. Its optimized cross-section provides great anti-extrusion capacity under high pressure, effectively resisting extrusion damage during continuous reciprocating motion. It can maintain stable sealing performance at working pressure up to 35 MPa, and the operating temperature ranges from -30℃ to 100℃.
Compatible with mineral hydraulic oil and most standard hydraulic fluids, HBR hydraulic rod seals are widely used in excavators, forklifts, injection molding machines and various industrial hydraulic cylinders. It matches standard seal groove dimensions for easy installation and direct replacement. With low leakage rate and prolonged service life, HBR piston rod seal delivers a reliable and cost-effective dynamic sealing solution for heavy-duty hydraulic applications.
