The BSL‑type piston rod seal is a reliable single‑acting hydraulic sealing element intended for reciprocating piston‑rod movement in hydraulic cylinder systems. Formulated with high‑performance polyurethane blended materials, this rod seal possesses excellent wear resistance, pressure resistance and anti‑extrusion capacity, keeping stable sealing performance under frequent load changes and harsh field operating conditions.
Adopting precision‑tuned sealing lip profile, the BSL‑type piston rod seal generates even contact pressure on the piston rod surface. It effectively prevents hydraulic oil leaking out of the cylinder. Moderate friction property restrains stick‑slip phenomenon during low‑speed reciprocating motion and reduces frictional heat build‑up during long‑time continuous operation. It maintains good adaptability to most common mineral‑based hydraulic fluids for engineering machinery.
Designed for standard sealing grooves, the BSL‑type piston rod seal allows simple installation and convenient spare‑part replacement. It is extensively used for excavators, construction machinery, lifting devices, agricultural hydraulic cylinders and various industrial hydraulic equipment. Applying BSL‑type piston rod seal helps cut oil leakage loss, slow down component abrasion, reduce maintenance frequency and improve the overall service life of sealing assemblies for your heavy‑duty hydraulic machinery.
