CX330 Hydraulic Boom Cylinder for CASE Excavator Spare Parts KSV1394 Aftermarket High Quality

This robust boom hydraulic cylinder is a direct interchange aftermarket spare exclusively customized for CASE CX330 medium-heavy crawler excavator, widely applied in municipal infrastructure, highway subgrade construction, housing foundation excavation and medium-sized quarry aggregate loading. As the core load-bearing lifting hydraulic component of front working devices, it delivers steady lifting, descending and load-locking power under long-duration alternating heavy loads, becoming a core stocked part for professional CASE equipment maintenance shops, mid-scale excavation rental fleets and cross-border spare parts merchants focused on CASE CX series construction excavators.

All manufacturing procedures strictly follow CASE original OEM design blueprints and high-precision assembly tolerances. Mount lug spacing, pin hole inner diameter, wear-resistant bronze bushing size and hydraulic oil port angle fully match the dedicated part number KSV1394. Pure bolt-on installation without on-site cutting, grinding or welding rework, effectively cutting manual maintenance costs and avoiding economic losses caused by long construction shutdowns resulting from cylinder breakdown.

1. Exclusive Dimensional Matching Only for CASE CX330 Excavator

   Part No.KSV1394 is tailor-made boom cylinder dedicated to CASE CX330, incompatible with other CX series models such as CX300 or CX350. All connection geometric dimensions fully restore genuine CASE OEM components, perfectly matching factory boom linkages and supporting hydraulic pipelines. It completely avoids assembly offset problems that lead to early seal aging and continuous oil leakage caused by forced installation on reinforced medium-heavy machine frames.

2. CX Series Medium-Heavy Construction Optimized Anti-Wear Reinforced Structure

   Different from low-cost universal thin-wall hydraulic cylinders unable to sustain long-term heavy earthmoving loads, this model optimizes cylinder tube and cast lug wall thickness targeting the high-frequency medium-heavy working characteristics of CASE CX330. It balances daily digging, lifting and loading demands, with service life far exceeding ordinary non-targeted reinforced aftermarket alternatives.

3. Two Independent Offline Factory Inspections to Eliminate Hidden Defects

   Each finished boom cylinder passes two strict offline testing procedures before leaving the factory. Full-stroke reciprocating fatigue test simulates months of uninterrupted municipal construction earthmoving work to test overall structural stability; long-time high-pressure soaking tightness inspection fully checks all internal and external leakage points. All unqualified products are completely screened out before warehousing to prevent unexpected construction work stoppage losses for end customers.

4. High Cost Performance for CASE CX330 Excavator Fleet Owners

   Original CASE OEM spare parts for CX330 have high retail prices and long procurement lead times. This aftermarket boom cylinder achieves equivalent structural strength, stable low-vibration operation and service life as genuine factory parts at a competitive unit price, significantly reducing long-term repeated maintenance expenses for independent repair garages and medium-sized rental enterprises equipped with batches of CX330 excavators.

5. Diversified Global Logistics Modes to Meet Different Customer Delivery Demands

   All in-stock products can be shipped within 3 working days after payment confirmation. Air express supports emergency rush orders for sudden machine breakdowns at remote suburban construction sites; consolidated bulk sea freight and full FCL container transportation provide cost-effective wholesale shipping plans for machinery distributors covering municipal construction markets in Africa, Southeast Asia, the Middle East and Latin America.

Our factory has more than ten years of professional R&D and mass production experience in hydraulic cylinders for CASE CX series medium-heavy excavators, with CX330 as one of our core mature production models. We own complete supporting production lines including heavy precision forging, deep inner honing, integral heat treatment and automatic chrome plating, equipped with professional medium-heavy load simulation test benches to restore real municipal construction working environments and continuously optimize product anti-shock durability. Our construction-grade aftermarket hydraulic cylinder product line is exported to dozens of countries all year round, winning stable long-term cooperative trust and consistent positive evaluations from global medium machinery spare parts distributors with precise CX model matching and stable uniform quality.
