EC360B Hydraulic Boom Cylinder 14508896 151mm Bore 1580mm Stroke Aftermarket Excavator Spare Part
This high-performance aftermarket hydraulic boom cylinder is precisely manufactured as a direct replacement component for EC360B excavators. As a critical hydraulic driving part of the front working mechanism, it controls the lifting and lowering movement of the boom to undertake heavy digging, bulk material hoisting and large-area land leveling tasks. It is widely applied in open-pit mining, quarry exploitation, highway construction and large-scale infrastructure projects.
All products are produced strictly in line with original OEM technical specifications, featuring identical mounting dimensions, pin hole spacing and hydraulic port layout. Direct bolt-on installation can be completed on site without cutting, welding or any secondary modification work.

- Full OEM Dimensional Compatibility: Every structural dimension and assembly interface is consistent with the original factory design, connecting seamlessly with boom linkages and hydraulic pipelines to deliver stable long-hour continuous heavy-load operation.
- Mine-Grade Reinforced Construction: The cylinder barrel and connecting lugs adopt thickened optimized design, capable of enduring long-term cyclic heavy loads and frequent collisions in harsh mining and construction sites to greatly extend service life.
- Multi-Round Rigorous Pre-Delivery Inspection: Each finished cylinder undergoes repeated full-stroke cycle tests and high-pressure airtight leak detection, thoroughly eliminating hidden risks of internal and external oil leakage.
- Excellent Cost Efficiency: It achieves the same reliability and service life as genuine spare parts, effectively cutting repeated procurement costs for repair workshops and spare parts wholesalers.
- Flexible Global Logistics Solutions: In-stock goods can be dispatched within 3 working days. Air freight satisfies urgent delivery demands, while sea freight is the most economical choice for bulk wholesale orders.
Our factory has over ten years of professional experience focusing on the R&D and manufacturing of hydraulic cylinders for EC series excavators. We supply a complete set of boom, arm and bucket cylinders covering EC360B and other mainstream equipment models. Supported by mature production craftsmanship and full-process strict quality control systems, our products are exported to aftermarket markets across Africa, Southeast Asia and the Middle East all year round, gaining long-term trust and consistent favorable feedback from global partners.
Q1: Can this boom cylinder fit EC330B or EC380B excavator models?
A: No. Different excavator models are equipped with exclusive part numbers and unique structural dimensions, which are not interchangeable. Please confirm your excavator complete model code before placing orders.
Q2: Does the standard package include the matched 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 sea transportation?
A: Anti-rust oil is injected into the cylinder inner cavity, and 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 ocean transit.
Q4: Are there tiered volume discounts when purchasing a full set of boom + arm + bucket cylinders?
A: Yes. Complete cylinder set orders enjoy graded preferential pricing. Consolidated container shipment service is also available to lower customers' total logistics expenses.
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 seal replacement and professional remote troubleshooting guidance in a timely manner.
