Product Introduction

Main Functions 1. Bidirectional piston sealing: Specially designed for pistons of double‑acting hydraulic cylinders. It achieves pressure‑bearing sealing in both forward and reverse directions of the piston, prevents internal leakage of hydraulic oil. 2. Anti‑extrusion protection: The back‑up rings on both sides prevent the main rubber seal from being squeezed into the groove clearance under high pressure, avoiding seal damage and failure. 3. Radial guiding support for piston: POM guide rings bear the radial load of the piston, ensure coaxial reciprocating motion of the piston, reduce eccentric wear. 4. Anti‑twist and anti‑overturn performance: The special tooth‑shaped structure of the main seal resists twisting and turning‑over inside the groove, maintaining sealing performance under both static and dynamic conditions. 5. Integrated design: Combining sealing, anti‑extrusion and guiding functions into one assembly. It fits into a single piston groove, simplifies piston machining and sh
