EC460B Hydraulic Boom Cylinder 14508475 Aftermarket 160mm Bore 1630mm Stroke Excavator Spare Part
This heavy-duty aftermarket hydraulic boom cylinder is precisely manufactured as a direct replacement spare part for EC460B large excavators. As the core power component of the front working assembly, it controls the lifting and lowering movement of the boom to handle heavy digging, bulk material hoisting and large-area land leveling tasks. Widely applied in open-pit mining, quarry excavation, large highway construction and key infrastructure engineering projects.
All products are produced strictly complying with original OEM technical standards, 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 modifications.

- 100% OEM Perfect Fitment: All structural sizes and assembly interfaces fully match the original cylinder, seamlessly connecting boom linkages and hydraulic pipelines to guarantee stable continuous operation under long-term heavy loads.
- Mine-Optimized Reinforced Structure: Thickened cylinder barrel and connecting lugs are designed to adapt to harsh mine and quarry working conditions, resisting long-period cyclic loads and accidental collisions and greatly extending service life.
- Multi-Round Strict Pre-Delivery Inspection: Each finished cylinder undergoes repeated full-stroke cycle tests and high-pressure airtight leak detection, completely eliminating hidden oil leakage risks both internally and externally.
- High Cost Performance: Delivers identical stability and durability as genuine original parts, effectively cutting recurring procurement costs for repair shops and spare parts distributors.
- Flexible Global Logistics Support: In-stock goods can be dispatched within 3 working days. Air freight meets urgent delivery needs, while sea freight is the most economical solution for bulk wholesale orders.
