This heavy-duty aftermarket hydraulic boom cylinder is precision manufactured as a direct interchangeable replacement spare part for 320CL medium excavators. As the core hydraulic power component of front working assembly, it controls boom lifting and lowering to finish heavy digging, bulk material hoisting, ground leveling and loading tasks. Widely applied in municipal engineering, road reconstruction, stone quarries and medium-sized earthmoving projects.
All cylinders are strictly produced in accordance with OEM technical standards, with fully consistent mounting dimensions, pin hole spacing and hydraulic port layout. Direct bolt-on installation can be completed on site without cutting, welding or any secondary modifi ion work.

204-3614 and 2043614 are two coding formats for the same boom cylinder. All structural dimensions perfectly match original components, seamlessly connecting boom linkages and hydraulic pipelines to ensure stable continuous medium-heavy load operation.
Thickened cylinder barrel and connecting lugs are optimized for harsh quarry and construction environments, resisting long-term cyclic loads and accidental collisions to greatly extend service life.
Each finished cylinder undergoes repeated full-stroke cycle tests and high-pressure airtight leak detection, completely eliminating hidden internal and external oil leakage risks.
It delivers identical stability and durability as genuine OEM spare parts, effectively cutting recurring procurement costs for repair shops and spare parts wholesalers.
In-stock goods can be dispatched within 3 working days. Air freight meets urgent breakdown orders; sea freight offers the most cost-effective solution for bulk wholesale shipments.
Our factory has more than ten years of mature experience in R&D and manufacturing hydraulic cylinders for classic CL series excavators including 320CL. We supply complete boom, arm and bucket cylinder assemblies with sophisti ed production craftsmanship and full-process strict quality control systems. Our aftermarket hydraulic cylinders are exported to aftermarket markets across Africa, Southeast Asia and the Middle East all year round, winning long-term trust and consistent favorable feedback from global spare parts dealers.
