Product Introduction

The 3463540417 Sun Gear is a key internal component of the wheel planetary reduction system used on Mercedes-Benz and MAN heavy-duty trucks. It is installed at the center of the planetary gear mechanism and works together with planetary gears, ring gear, and carrier assembly to transfer power and increase wheel torque output.

The planetary reduction system is designed to reduce wheel speed while increasing torque, allowing heavy trucks to achieve stronger traction and better load-carrying capability. The sun gear serves as the driving gear of the planetary mechanism and directly affects the efficiency and stability of the final drive system.

During long-term heavy-duty operation, the sun gear is continuously exposed to high torque, repeated gear meshing, and impact loads. Wear, tooth damage, surface fatigue, or improper lubrication may lead to abnormal wheel hub noise, overheating, vibration, and reduced transmission efficiency.

The 3463540417 sun gear is manufactured from high-strength alloy steel through precision forging, CNC gear machining, and heat treatment processes. The optimized tooth profile provides excellent contact strength, fatigue resistance, and wear durability, ensuring smooth engagement with related planetary components.

Designed according to OEM specifications, this sun gear provides reliable replacement compatibility for Mercedes-Benz Actros, Axor, NG, SK, Econic, North Benz, and MAN truck wheel reduction axle systems. It is widely used for hub reduction repair, axle overhaul, fleet maintenance, and aftermarket drivetrain replacement applications.

Each sun gear undergoes strict quality inspections including tooth accuracy testing, hardness testing, dimensional verification, surface finish inspection, and assembly compatibility testing to ensure dependable performance and extended service life.
