   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.

   SPARKLING MACHINERY NEW 600-467-4300 Controller is a core electronic control unit for compatible Komatsu excavator models (construction/mining use). It processes operational signals, coordinates hydraulic, electrical, and engine systems, and ensures precise equipment performance. 
   Meeting Komatsu OEM standards (600-467-4300), it resists -30°C to 85°C temps, electromagnetic interference, and vibration, guaranteeing seamless compatibility and long-term reliable system control.
