Manufactured with high-precision machining and quality-tested materials, the 7051235250 gear pump offers excellent reliability, extended service life, and consistent performance under extreme working conditions. Whether you're replacing a worn-out unit or conducting scheduled maintenance, SPARKLING MACHINERY's aftermarket gear pump ensures optimal compatibility and long-term value.

   SPARKLING MACHINERY NEW EX270 EX270-5 EX280H-5 EX300 EX300-2 EX300-3 4067720 Bushing is a critical wear-resistant component for Hitachi EX270, EX270-5, EX280H-5, EX300, EX300-2, and EX300-3 excavators (widely used in construction, mining, and earthmoving projects). As the "joint buffer", it reduces friction between moving parts (e.g., boom hinges, arm connections) during tasks like digging, lifting, and swing operations—preventing metal-to-metal wear, absorbing vibration, and ensuring smooth movement of hydraulic structures.
   Meeting Hitachi OEM standards (part no. 4067720), it endures -30°C to 100°C working temperatures, resists corrosion and impact, and maintains stable dimensional accuracy. Strict testing guarantees seamless compatibility with the six Hitachi models and long-term reliability of excavator structural joints.

   SPARKLING MACHINERY NEW 14704262 Center Swivel Joint is a premium China-made hydraulic connection component designed for compatible excavators. As a critical link between the excavator’s fixed lower structure (undercarriage) and rotating upper structure (cabin, boom, and working arms), it enables uninterrupted 360° rotation while maintaining seamless hydraulic fluid transmission to core systems—including swing motors, hydraulic cylinders, and control valves. This ensures consistent power delivery for essential operations like digging, lifting, and precision swing movements in construction, mining, and earthmoving tasks.

   Engineered to original equipment standards, it maintains leak-free performance even under high hydraulic pressure (up to industry-standard thresholds) and continuous rotational stress, as well as harsh working conditions such as dust, vibration, and exposure to construction debris or moisture. With optimized high-wear-resistance sealing rings and precision-machined internal flow channels, it minimizes pressure loss and prevents fluid contamination, protecting the hydraulic system from damage. Backed by strict quality verification, it guarantees reliable operation to support uninterrupted machinery rotation and maximize work efficiency.

The VOE14512954 Swing Motor Seal Kit by SPARKLING MACHINERY is designed for Volvo EC460B excavators. Built with durable rubber and PTFE, it ensures excellent sealing, heat resistance, and long-lasting swing motor performance—ideal for heavy-duty maintenance and hydraulic repairs.
