This high-quality aftermarket hydraulic boom cylinder is precisely engineered as a direct replacement for CASE 9010B crawler excavators (produced 1995-2000). As the core component of the excavator's working system, it controls the lifting and lowering of the boom, enabling efficient digging, loading and material handling operations in construction sites, road building, quarrying and agricultural engineering projects. All units are manufactured to meet original CASE OEM specifications, with identical mounting dimensions, pin hole spacing and hydraulic port layout. Operators can complete direct bolt-on installation on site without any cutting, welding or secondary modification work.

1. Perfect CASE OEM Compatibility: Matches the original component in all structural sizes, connecting seamlessly with boom linkages and hydraulic pipelines to ensure stable running after installation.
2. Heavy-Duty Design for CASE 9010B: Reinforced cylinder barrel and connecting lugs specifically engineered to handle the 21-ton operating weight of CASE 9010B excavators, capable of bearing long-term cyclic loads and occasional impacts in harsh construction environments.
3. Precision Manufacturing: Each cylinder undergoes computer-controlled honing and grinding processes to ensure consistent dimensions and surface finish, minimizing friction and extending seal life.
4. Comprehensive Quality Assurance: 100% of finished cylinders pass full-stroke reciprocating test (≥500 cycles) and high-pressure airtight test (10 minutes at test pressure) to eliminate internal and external oil leakage risks.
5. Cost-Effective Alternative: Delivers performance equivalent to genuine CASE parts while significantly reducing procurement costs (typically 30-50% savings) for maintenance workshops and equipment owners.
6. Flexible Logistics Options: In-stock items can be dispatched within 3 working days. Air freight is available for urgent orders, while sea freight is recommended for bulk purchases to save costs.
