SK300LC II SK300 II Hydraulic Bucket Cylinder for Kobelco Excavator Spare Parts 2406N1004F1 Aftermarket High Quality

More Branded Accessories are Available

This high-load bucket hydraulic cylinder is tailor-made aftermarket replacement matching Kobelco second-generation SK300 standard track excavator and long-track SK300LC II large machine. As the core executive hydraulic component of digging attachment, it drives bucket clamping, rock grabbing and bulk material dumping, widely deployed in open quarries, large highway earthworks, mine ore loading and heavy infrastructure construction projects. It has become a mainstream stocked spare part for heavy equipment repair workshops, large construction rental fleets and cross-border dealers focusing on classic Kobelco second-gen large excavators.

Production strictly complies with original Kobelco industrial drawings and OEM dimensional benchmarks. Mounting lug spacing, pin hole aperture and hydraulic oil port layout are fully consistent with part number 2406N1004F1. Direct bolt-on installation without cutting, grinding or welding modification, greatly shortening on-site maintenance cycle and reducing construction halt losses.

1. Universal Fit for Standard & Long-Track SK300 II Series

   One cylinder fits both SK300 II and extended chassis SK300LC II perfectly. All connecting dimensions completely replicate original 2406N1004F1 parts, seamlessly matching bucket linkages and original hydraulic pipelines. No forced assembly, effectively avoiding seal aging and oil leakage caused by dislocation installation.

2. Quarry-Specific Reinforced Anti-Impact Design

   Thickened cylinder barrel and integrated cast lug plates are upgraded for long-term heavy rock digging scenarios. The reinforced structure resists continuous heavy cyclic loads and frequent sharp rock collisions, delivering far longer service life than ordinary thin-wall aftermarket cylinders for light construction.

3. Two Independent Pre-Delivery Inspections Eliminate Hidden Malfunctions

   Each finished cylinder undergoes dual strict testing procedures: full-stroke reciprocating fatigue test to simulate months of non-stop mining operation and verify structural stability; high-pressure soaking airtight inspection to check all internal and external leakage points. Defective products are fully screened out before warehousing to prevent sudden site breakdown.

4. Superior Cost Performance for Large Heavy Equipment Operators

   It achieves equivalent structural toughness, stable operation and service cycle as genuine Kobelco OEM spare parts with much lower procurement cost, effectively cutting long-term repeated spare part expenses for mine repair factories and large heavy machinery rental companies with SK300 II fleets.

5. Diversified Global Logistics Solutions to Meet Varied Client Needs

   In-stock products can be shipped out within 3 working days after payment confirmation. Air freight serves emergency rush orders for sudden mine breakdown repairs; consolidated bulk sea cargo and full FCL container transport offer cost-effective wholesale solutions for machinery distributors covering Africa, Southeast Asia, Middle East and Latin American mining markets.

Our workshop has over 10 years of dedicated R&D and mass production experience for hydraulic cylinders of Kobelco second-generation large excavators including SK300 II / SK300LC II.
