The BSN‑type piston rod seal is a heavy‑duty single‑acting hydraulic sealing component designed for reciprocating piston‑rod motion inside hydraulic cylinders. Constructed from high‑toughness polyurethane compound material, this rod seal delivers outstanding wear resistance, high‑pressure tolerance and strong anti‑extrusion performance, maintaining stable sealing output under cyclic heavy‑load and fluctuating‑pressure working environments.
Featuring optimized dual‑lip geometry, the BSN‑type piston rod seal creates uniform contact pressure against piston‑rod surfaces. Retained lubricant between sealing lips effectively reduces dry friction, suppresses stick‑slip during low‑speed reciprocation and lowers heat accumulation during continuous operation. It reliably blocks hydraulic oil leakage outward from cylinder chambers while resisting medium erosion, even under zero‑pressure standby conditions.
Matching standard installation grooves, the BSN‑type piston rod seal supports straightforward assembly and convenient spare‑part replacement. It is widely deployed for excavators, construction machinery, lifting equipment, agricultural hydraulics and general‑purpose industrial hydraulic cylinders. Equipped with BSN‑type piston rod seal, your hydraulic system achieves less fluid loss, reduced component abrasion, lower maintenance frequency and longer overall service life for sealing assemblies in harsh field conditions.
