High-Performance RHC61A Turbocharger for Powered Excavators & Construction Machinery

• Broad Machinery Compatibility: This RHC61A unit is the primary boost solution for W04/W06 series engines, which power an extensive range of Japanese construction equipment. Whether it's a excavator or a Sakai road roller, this turbo provides the consistent pressure needed for high-load hydraulic cycles and drive traction.
• Severe-Duty Thermal Protection: The turbine housing is cast from high-resistance ductile iron, engineered to handle the sustained heat generated by industrial diesel engines during 24/7 operations. This metallurgy prevents housing cracking and warping, ensuring structural integrity even in remote or high-load environments.
• Precision VSR Dynamic Balancing: To ensure maximum service life and prevent bearing failure, every core assembly (CHRA) is balanced on a high-speed Vibration Sorting Rig (VSR). By eliminating shaft oscillations at speeds exceeding 100,000 RPM, we protect the internal journal bearings from premature wear and prevent the common "turbo whine."
• Low-End Torque Synchronization: The aerodynamics of the compressor and turbine wheels are optimized to reduce rotational inertia. This provides rapid boost response at lower engine speeds, giving your machinery the immediate hydraulic power required for aggressive digging and lifting operations.
• True "Plug-and-Play" Installation: This unit is a precision 1:1 replacement for original brand factory turbos. All mounting flanges, oil inlets, and air connections are machined to exact 24100-2940A specifications, allowing for a seamless installation without modifications to the exhaust manifold.

Fengcheng Zhongke Turbocharger Co., Ltd. is a leading high-tech factory specializing in the R&D, production, and global distribution of high-performance turbochargers. Based in Fengcheng—one of the world’s most renowned turbocharger manufacturing hubs—we have grown from a local workshop into a global supplier, serving heavy-duty, commercial, and passenger vehicle markets worldwide.

At Zhongke, we don't just "make" parts.we engineer reliability.

• Material Integrity: We exclusively use K18 Nickel-Alloy turbine wheels, capable of withstanding extreme exhaust temperatures (up to 950°C) without deformation.
• Dynamic Balancing: 100% of our turbochargers undergo high-speed dynamic balancing tests at 150,000+ RPM to guarantee zero vibration and extended bearing life.
• Certified Quality: Our production processes are certified under ISO 9001 and IATF 16949, the gold standards for the global automotive and heavy-machinery industries.

Manufacturing Prowess:Our facility is equipped with state-of-the-art production lines, including precision 5-Axis CNC machining centers, high-speed VSR (Vibration Sorting Rig) balancing machines, and advanced material testing labs.

Our Specialization:We maintain a vast inventory of over 3,500+ turbocharger models, with a focus on heavy-duty and construction machinery engines. Focused on optimizing fuel efficiency and restoring factory horsepower, our passenger car turbos are engineered with the same precision and K18 heat-resistant materials as our industrial line, ensuring reliable performance for daily commuting and high-speed driving alike.
