Hitachi EX series excavator hydraulic cylinders are designed for boom, arm, and bucket applications across a wide range of Hitachi excavator models. These hydraulic cylinders are manufactured to match OEM dimensions and performance requirements, providing accurate fitment, stable operation, and consistent load handling in heavy-duty construction and earthmoving environments.
Yoonad Hydraulics supplies replacement hydraulic cylinders compatible with Hitachi EX series excavators, covering common models such as EX120, EX200, EX220, EX300, EX350, and EX400. Each cylinder is produced using high-strength honed tubes, induction-hardened and hard-chrome-plated piston rods, and reliable sealing systems to ensure smooth motion, pressure stability, and long service life under continuous operating conditions.
All Hitachi EX series excavator hydraulic cylinders are CNC-machined and pressure-tested before delivery. Custom specifications, including bore size, stroke length, mounting dimensions, and sealing configurations, are available to support equipment repair, cylinder rebuilding, and aftermarket replacement needs.
