BSL type piston rod seal is a single-acting reciprocating hydraulic rod seal customized for hydraulic cylinder piston rods. It features an optimized asymmetrical lip profile with pressure self-energizing sealing mechanism. When hydraulic pressure increases, the sealing lip tightly contacts the rod surface to stop internal hydraulic fluid leakage and keep external dust, grit and moisture out of the cylinder.
Fabricated from premium polyurethane material, the BSL piston rod seal delivers outstanding wear resistance, superior tear strength and low friction. Its refined cross-section provides strong anti-extrusion capability under high pressure, avoiding extrusion damage and deformation during continuous reciprocating motion. It can maintain stable sealing performance under working pressure up to 35 MPa, operating temperature ranging from -30℃ to 100℃.
Compatible with mineral hydraulic oil and most conventional hydraulic fluids, BSL hydraulic rod seals are widely applied in excavators, forklifts, injection molding machines and various industrial hydraulic cylinders. It matches standard seal groove sizes for easy installation and direct replacement. With low leakage rate and longer service life, the BSL piston rod seal provides a dependable and economical dynamic sealing solution for heavy-duty hydraulic systems.
