EX450LCH-5 EX450H-5 Hydraulic Bucket Cylinder for Hitachi Excavator Spare Parts

This heavy-duty aftermarket hydraulic bucket cylinder is designed as a direct replacement component for Hitachi EX450LCH-5 and EX450H-5 large heavy-load excavators. As a core hydraulic executing part of the front working attachment, it drives the bucket to complete powerful digging, material grabbing and dumping operations, perfectly suited for open-pit mining, stone quarrying, large-scale infrastructure construction and heavy earthmoving projects.

All products are manufactured strictly following Hitachi original OEM technical specifications, with fully consistent installation dimensions, pin hole spacing and hydraulic port layout. On-site direct bolt-on installation can be finished without cutting, welding or any secondary modification work.

1. 100% OEM Interchangeable Fitment: All structural dimensions and assembly interfaces match the original cylinder completely, connecting seamlessly with bucket linkages and hydraulic pipelines to sustain stable continuous heavy-load operation.
2. Mine-Grade Reinforced Structure: Thickened cylinder barrel and connecting lugs are optimized for long-term heavy impact working conditions in mines and quarries, effectively resisting cyclic loads and external collisions to extend service life greatly.
3. Multi-Round Strict Pre-Delivery Inspection: Each finished cylinder undergoes repeated full-stroke cycle tests and high-pressure airtight leak detection, thoroughly eliminating hidden troubles of internal and external oil leakage.
4. Outstanding Cost Performance: Delivers identical stability and durability as genuine Hitachi original spare parts, helping maintenance workshops and spare parts wholesalers cut long-term repeated procurement costs notably.
5. Flexible Global Logistics Scheme: In-stock products can be dispatched within 3 working days. Air freight meets urgent delivery demands, while sea freight is the most economical choice for bulk wholesale orders.

Q1: Can this bucket cylinder fit regular EX450LC-5 or EX450-5 standard excavators?

A: No. EX450LCH-5 and EX450H-5 are long arm heavy-duty customized versions, equipped with exclusive part numbers and unique structural dimensions, which cannot be interchanged with standard models. Please double-check your excavator full model code before ordering.

Q2: Does the standard package include the matching seal repair kit?

A: The seal repair kit is not included in standard delivery. You can purchase the dedicated supporting seal kit separately, and we will offer a competitive combined order quotation.

Q3: What packaging is adopted for long-distance overseas ocean transportation?

A: Anti-rust oil is injected into the cylinder inner cavity, anti-rust grease is evenly coated on the piston rod surface; the whole cylinder is wrapped with waterproof PE film and packed in reinforced export plywood cases to avoid collision and moisture damage during long-distance sea transit.

Q4: Are there tiered discount policies when purchasing a full set of boom + arm + bucket cylinders?

A: Yes. Complete cylinder set orders enjoy graded volume discounts. We also provide consolidated container shipment service to lower total logistics costs for customers.

Q5: What after-sales technical support can be provided if oil leakage occurs within the warranty period?

A: Please provide clear photos of the leakage position and the excavator serial number. We will arrange free replacement of sealing components and professional remote troubleshooting guidance promptly.
