MYR‑Type piston rod seal is a single‑acting hydraulic rod seal engineered for reciprocating piston rods in hydraulic cylinders. Constructed with a specially optimized Y‑shaped lip profile, this seal creates uniform contact pressure against the rod surface once hydraulic pressure is applied, delivering reliable fluid containment and minimizing oil leakage during continuous back‑and‑forth motion.
Made from high‑performance polyurethane, the MYR rod seal features outstanding wear resistance and anti‑extrusion capability. It can operate steadily under medium to high pressure working conditions, resisting abrasion caused by frequent reciprocation. Its compact cross‑section fits standard seal grooves, enabling simple installation without special modification to cylinder parts.
This hydraulic rod seal is widely adopted in engineering machinery, injection molding machines, and general industrial hydraulic equipment. The MYR‑type lip design balances low friction and sealing performance, reducing heat generation and extending the service life of both the seal and matching piston rod. Paired properly with wiper seals and guide rings, it forms a complete sealing system for hydraulic cylinders. It is a dependable sealing choice for users looking for stable performance and lower maintenance costs in hydraulic applications.
