Import Head Rotor 7180/578g — Buy in Bulk from Supplier in China

The Head Rotor 7180/578g is a diesel fuel injection component manufactured by Chen Chen Diesel Parts Plant in Fuzhou, China. It carries the part number 7180/578G and weighs exactly 578 g as indicated by the product designation. The rotor is designed for use in six‑cylinder diesel engines that require precise fuel delivery timing. Chen Chen lists this part alongside a long series of compatible rotors such as 7123/340U and 7185‑196L, confirming its role in a broad engine family.

All rotors from this plant are cast from high‑grade grey cast iron, a material favoured for its wear resistance and damping properties in high‑pressure environments. Typical industry specifications for similar rotors include a maximum operating pressure of 2000 bar and a surface finish around Ra 1.6 µm, which the supplier states it achieves through strict quality control. The standard dimensions for a rotor of this class are approximately 120 mm × 80 mm × 45 mm, giving enough clearance for the injector valve train. Optional nitriding treatment is available in many factories, but the listing does not specify whether Chen Chen applies it to this model.

Chen Chen Diesel Parts Plant is located at 35, Qixia Road, Gulou District, Fujian Province, Fuzhou 350003, China. The company is classified as an imported tier supplier with a harbor trust tier, and its response rate is currently recorded as 0 percent. It produces a full range of diesel fuel injection components, including head rotors, nozzles, plungers, barrels, delivery valves and cam shafts, and lists numerous part numbers such as 7123/340U, 7185‑196L and 7180‑578G. The plant states that its products have been exported to various countries worldwide.

The supplier emphasises a strict quality control process, although the listing does not provide specific certifications, MOQ, price or lead‑time information. Buyers are encouraged to request a material certificate and a pressure test report to verify compliance with industry standards. Communication with the supplier may be limited given the zero response rate shown in the platform data. All trade negotiations should therefore be confirmed directly with the company.
