High-precision forged oil pump gears (18Xh3a steel)

Excellent material

It uses 18Xh3a (or 18CrNi4A) high-grade carburizing steel.

This material possesses high toughness, good core strength, and excellent carburizing and quenching properties.

It can ensure that gears maintain high wear resistance and fatigue strength under heavy loads and impact loads.

Advanced technology

1. Precision forging: The blank is formed by die forging, and the fiber flow lines are continuously distributed along the tooth profile. Compared with directly machined parts, its strength, impact resistance and service life are greatly improved.
2. Surface finishing: The tooth profile is precision ground to achieve a national standard (GB) level 6 or higher precision, ensuring smooth transmission, low noise, and high efficiency, meeting the stringent requirements of oil pump systems for flow stability.

Reliable performance

The product undergoes rigorous heat treatment (such as carburizing, quenching, and tempering) and precision machining.

It features high surface hardness (e.g., HRC 58-62), good core toughness, and dimensional stability.

It is designed specifically for the continuous, high-speed lubrication environment inside the engine.

Precise application

Designed specifically for engine lubrication pumps (oil pumps) in trains, diesel locomotives, and large construction machinery.

It is a key component to ensure reliable lubrication and normal operation of the engine.
