Strong JCM series excavator hydraulic cylinders are designed for boom, arm, and bucket applications across a wide range of JCM excavator models. Manufactured to meet OEM dimensional and performance standards, these hydraulic cylinders provide accurate fitment, stable motion control, and consistent performance in demanding construction, earthmoving, and quarrying environments.
Yoonad Hydraulics supplies replacement hydraulic cylinders compatible with Strong JCM series excavators, including models such as JCM130, JCM160, JCM200, JCM220, JCM250, and JCM300. Each cylinder is produced using precision‑honed steel tubes, induction‑hardened and hard‑chrome‑plated piston rods, and high‑quality sealing systems to support pressure stability, reduced internal leakage, and extended service life under continuous operation.
All Strong JCM series excavator hydraulic cylinders are CNC‑machined and pressure‑tested before shipment. Custom bore sizes, stroke lengths, mounting configurations, and seal options are available to support cylinder repair, rebuilding, and aftermarket replacement requirements.
