Product Introduction

The 6743560226 Grooved Locking Nut is a critical fastening component used in the rear axle assemblies of Mercedes-Benz Actros MP1 / MP2 and MAN TGA / TGM / F2000 heavy-duty trucks. It is designed to securely lock bearings, wheel hubs, differential shafts, and other drivetrain components while maintaining the required preload for safe and reliable operation.

Its grooved design allows the nut to be used together with locking washers or retaining plates, preventing loosening caused by continuous vibration, heavy loads, and shock during commercial vehicle operation. Proper preload helps extend the service life of bearings, gears, and axle components.

The 6743560226 nut is manufactured from premium alloy steel through precision forging, CNC thread machining, and heat treatment. It features high tensile strength, accurate thread dimensions, excellent fatigue resistance, and superior corrosion resistance for long-term durability in demanding working environments.

Designed according to OEM specifications, this locking nut provides direct replacement compatibility for Mercedes-Benz Actros MP1 / MP2 and MAN TGA / TGM / F2000 axle systems. It is widely used for rear axle rebuilding, differential repair, wheel hub servicing, commercial fleet maintenance, and aftermarket drivetrain overhaul. This OEM number is commonly identified as a grooved nut for Mercedes and MAN axle applications.

Each nut undergoes strict OEM-quality inspections including thread accuracy testing, hardness verification, dimensional inspection, and torque performance testing to ensure dependable fastening performance and extended service life.
