SPARKLING Excavator Swing Reducer – Reliable & Precise Parts

Heavy-Duty Swing Gearbox Reducer for Hitachi JS Excavators
Engineered for JS200, JS210, JS220, JS220LR, and JS235 excavators, the Swing Gearbox Reducer (JRC0007) is the precision heart of your machine’s rotation system. This OEM-compatible reducer delivers unmatched torque transmission and smooth 360° slewing motion under extreme loads. Forged with hardened helical gears and triple-sealed bearings, it resists wear, minimizes backlash, and withstands relentless job site vibrations. SPARKLING MACHINERY’s JRC0007 undergoes rigorous cycle testing to ensure perfect meshing alignment and extended service life – because precise rotation isn’t a luxury, it’s the core of your excavator’s productivity.

   SPARKLING MACHINERY NEW EC200B EC235D EC200D VOE14541069 Swing Reducer is a dedicated power transmission component exclusively designed for EC200B, EC235D, and EC200D excavators. As the core of the excavator’s swing system, it reduces the high-speed input from the swing motor to generate high torque, enabling smooth, controlled 360° rotation of the upper structure (cabin, boom, and bucket). This function is critical for precise positioning during digging, loading, and material handling tasks in construction, mining, and earthmoving scenarios—ensuring the excavator operates with stability and accuracy even under heavy loads.

   Engineered to match original equipment performance standards, it maintains reliable torque output and rotational smoothness even in harsh working conditions, such as intense vibration, dust, and temperature fluctuations. It prevents rotational lag or jitter, safeguards the swing motor from overload damage, and supports continuous operation to minimize workflow interruptions. Backed by strict performance verification, it guarantees long-term operational stability for the excavator’s swing function.

   SPARKLING MACHINERY NEW VOE14743548/11224414 Swing Reducer is a core transmission component for Volvo EC380D and SDLG E6400F excavators (mining/heavy construction use). It reduces speed to amplify torque, enabling smooth, precise upper-structure swinging for heavy-load tasks. 
   Meeting OEM standards (dual part numbers), it resists -30°C to 100°C temps, heavy loads, and wear, guaranteeing seamless compatibility and long-term reliable swing performance.

   SPARKLING MACHINERY NEW VOE14622901/14680015 Swing Reducer is a core transmission component exclusively for Volvo EC380D excavators (mining/heavy construction use). It reduces engine speed to amplify torque, enabling smooth, precise upper-structure swinging for heavy-load tasks like deep excavation. 
   Meeting Volvo OEM standards (dual part numbers), it resists -30°C to 100°C temps, heavy loads, and wear, guaranteeing seamless EC380D compatibility and long-term reliable swing performance.
