Product Introduction

The 3463540412 Axle Ring Gear is one of the most important transmission components inside the rear axle differential system of Mercedes-Benz, Beiben, and MAN heavy-duty trucks. Working together with the drive pinion, it forms the final drive gear set responsible for transmitting engine torque from the driveshaft to the differential assembly and axle shafts.

The ring gear converts rotational power while providing the required gear reduction ratio for heavy-duty commercial vehicles. Accurate gear tooth geometry and precision machining ensure smooth gear engagement, efficient torque transmission, low operating noise, and balanced load distribution throughout the drivetrain.

During continuous heavy-load transportation, the ring gear is subjected to extremely high torque, cyclic loading, and continuous gear contact. Excessive wear, pitting, broken teeth, or poor gear contact may lead to abnormal differential noise, vibration, overheating, reduced transmission efficiency, and premature axle failure.

The 3463540412 axle ring gear is manufactured from premium alloy steel using precision forging, CNC gear cutting, carburizing, quenching, precision grinding, and lapping processes. The hardened gear teeth provide excellent surface hardness, high contact strength, superior fatigue resistance, and long-lasting durability under severe working conditions.

Designed according to OEM specifications, this ring gear provides direct replacement compatibility for Mercedes-Benz Actros MP1 / MP2, Axor, NG, SK, Econic, Beiben NG80, and MAN TGA / TGM / F2000 axle systems. It is widely used for differential rebuilding, rear axle overhaul, commercial fleet servicing, and aftermarket drivetrain repair.

Each ring gear undergoes strict OEM-quality inspections including gear profile measurement, hardness testing, tooth contact pattern inspection, dimensional verification, and material quality analysis to ensure dependable performance and extended service life.
