Product Introduction

The 3463541109 Carrier Hub / Ring Gear Support is a critical structural component used inside the rear axle differential assemblies of Mercedes-Benz, Beiben, and MAN heavy-duty trucks. It serves as the mounting and support base for the ring gear (crown wheel) and differential carrier, maintaining precise alignment of the final drive gear set during operation.

The carrier hub supports the differential assembly while accurately locating the ring gear relative to the drive pinion. This precise positioning is essential for achieving proper gear contact patterns, reducing transmission noise, minimizing vibration, and maximizing drivetrain efficiency.

During heavy-duty commercial operation, the carrier hub is subjected to high torque, heavy axle loads, continuous vibration, and cyclic stress. Damage, deformation, or excessive wear can cause incorrect gear backlash, abnormal differential noise, accelerated gear wear, bearing failure, and reduced axle reliability.

The 3463541109 carrier hub / ring gear support is manufactured from premium forged alloy steel using precision forging, CNC machining, and advanced heat treatment processes. Its accurately machined bearing seats and mounting faces ensure excellent concentricity, superior rigidity, and long-term durability under demanding working conditions.

Designed according to OEM specifications, this carrier hub 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 maintenance, commercial fleet servicing, and aftermarket drivetrain repair.

Each component undergoes comprehensive OEM-quality inspections including dimensional verification, concentricity testing, hardness testing, mounting surface inspection, and material quality analysis to ensure reliable performance and extended service life.
