   SPARKLING MACHINERY NEW PC27MR PC30MR PC35MR PC45MR PC490 PC55MR 708-3S-14290/708-3S-14250 Piston Subassembly is a dedicated, high-performance hydraulic component exclusively engineered for KOMATSU PC27MR, PC30MR, PC35MR, PC45MR, PC490, and PC55MR crawler excavators—covering mini to heavy-duty models widely used in urban construction, landscaping, mining, and large-scale infrastructure projects. As a core part of the excavator’s hydraulic cylinder system, it converts hydraulic pressure into linear motion to drive key mechanisms (boom, arm, bucket), ensuring powerful and smooth operation during tasks like trench digging, rock breaking, and material loading. This function is vital for maintaining sufficient digging force, optimizing operational efficiency, and avoiding unplanned downtime caused by cylinder performance failures.

   Engineered to meet KOMATSU’s original equipment (OEM) standards and compatible with part numbers 708-3S-14290 and 708-3S-14250, the Piston Subassembly withstands harsh working conditions: high hydraulic pressure (up to 36 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from heavy-duty use. It resists oil contamination and mechanical wear, providing long-lasting power transmission reliability for the six KOMATSU excavator models. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily tasks.

   SPARKLING MACHINERY NEW A35E EC330B EC330C EC360B L220F PL4608 VOE21243114 Rocker is a key operational component for 6 Volvo heavy equipment models (mining/construction use). It enables precise actuation of core functions (e.g., hydraulic controls, auxiliary operations) with responsive performance, ensuring smooth equipment maneuvering. 
   Meeting Volvo OEM standards (VOE21243114), it resists -30°C to 85°C temps, wear, and vibration, guaranteeing seamless compatibility and long-term reliable operation.

   SPARKLING MACHINERY NEW R200W2 4472.320.056 Hub is a premium China-made core component specifically engineered for R200W2 wheel excavators. As a critical part of the undercarriage system, it serves as the central connecting unit between the wheel, axle, and hydraulic components, ensuring stable load distribution and smooth rotational movement during machinery operation.

   Designed to original equipment standards, it maintains precise alignment and high load-bearing capacity, performing reliably even under heavy workloads and continuous vibration. With enhanced structural stability and wear-resistant properties, it adapts seamlessly to harsh working environments, from rough construction sites to muddy terrain. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
