Import Diesel Injection Parts - Head Rotor — Buy in Bulk from Supplier in China

The head rotor is a precision component used in VE-type rotary diesel injection pumps, designed to meter and distribute fuel under high pressure to individual injectors. This part corresponds to part numbers such as 334-327, 334-378, and 334-475, matching applications in VW, Cummins, Volvo Penta, and Iveco engines. It is manufactured from hardened tool steel with a surface finish of Ra 0.4 μm, consistent with OEM wear resistance standards for high-cycle fuel delivery systems.

The material composition is typically SAE 52100 bearing steel or equivalent, heat-treated to HRC 58-62 for durability under abrasive fuel conditions. Tolerances on the rotor diameter and cam lobes are held within ±0.005 mm, which is standard for rotary pump components to ensure consistent fuel timing and flow. Surface hardness and dimensional stability are critical to prevent premature wear or leakage, especially in high-hour commercial and agricultural diesel engines.

These head rotors are primarily purchased by diesel repair shops, fleet maintenance providers, and OEM aftermarket distributors serving European and Asian commercial vehicle markets. Units are packaged in anti-corrosion paper with individual box labeling per part number. Bulk orders are accepted with standard lead times of 15 to 25 days, and FOB Putian port terms apply. Buyers should verify compatibility with their pump model using the original part code before ordering.
