SANY SY series excavator hydraulic cylinders are engineered for boom, arm, and bucket applications across a wide range of SY excavator models. Manufactured to OEM dimensional and performance standards, these hydraulic cylinders provide accurate fitment, controlled motion, and consistent performance in demanding construction, earthmoving, and mining environments.
Yoonad Hydraulics supplies replacement hydraulic cylinders compatible with SANY SY series excavators, including models such as SY75, SY95, SY135, SY155, SY215, SY235, SY305, and SY365. 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 SANY SY 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.
