   SPARKLING MACHINERY NEW EW140B EW160B EW180B 14390015 Controller is a premium China-made intelligent control component specifically engineered for EW140B, EW160B, and EW180B wheel excavators. As a core part of the machinery’s electrical system, it processes real-time operational data, regulates key functions such as engine performance, hydraulic flow, and auxiliary operations, ensuring synchronized and efficient equipment operation in construction, mining, and industrial applications.

   Designed to original equipment standards, it maintains stable signal transmission and responsive control even under continuous operation and harsh conditions. With advanced programming for optimized performance, it adapts seamlessly to varying workloads, minimizing operational errors and maximizing productivity. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW ZGAQ-02328 Taper Roller Bearing is a core rotating component for Hyundai excavators (construction/mining use). It withstands combined radial and axial loads, ensuring smooth rotation of key shaft parts. 
   Meeting Hyundai OEM standards (Part No.: ZGAQ-02328), it delivers high wear resistance and load capacity, guaranteeing seamless compatibility and long-term stable operational performance.

   SPARKLING MACHINERY NEW 3078150 Sensor is a dedicated precision detection component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As a core part of the machinery’s operational monitoring system, it real-time collects critical data—including hydraulic pressure, engine temperature, or component position—and transmits accurate signals to the machinery’s control unit. This function is essential for enabling the control system to adjust operations dynamically during heavy-duty tasks like digging, lifting, and grading, directly ensuring stable machinery performance, preventing overloading or overheating, and reducing the risk of unexpected component damage.

   Engineered to match original equipment performance standards, it maintains high signal accuracy and stable operation even under harsh working conditions, including continuous vibration, dust exposure, temperature fluctuations (-30°C to 80°C), and hydraulic oil contamination. It resists signal interference and mechanical wear, avoiding data errors or transmission failures that could lead to operational delays or safety hazards. Backed by strict performance verification, it guarantees reliable data feedback to support uninterrupted operation of compatible heavy-duty machinery.
