Hyundai R series excavator hydraulic cylinders are designed for boom, arm, and bucket applications across a wide range of R-series excavator models. Manufactured to OEM dimensional standards, these hydraulic cylinders provide accurate fitment, stable motion control, and consistent performance under demanding construction and mining conditions.
Yoonad Hydraulics supplies replacement hydraulic cylinders compatible with Hyundai R series excavators, including models such as R130, R150, R210, R220, R290, R300, and R360. 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 during continuous operation.
All Hyundai R 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.
