AZ9100413007 front axle I-beam is the main load-bearing skeleton of Sinotruk Howo heavy truck steering front axle. It adopts high-quality alloy steel forging and special heat treatment process, featuring high bending strength, good toughness and strong fatigue resistance. As the I-shaped main beam of the front axle assembly, it bears the vertical load from the vehicle weight and cargo, as well as impact loads caused by road bumps during driving. It provides installation base for steering knuckle, brake assembly, leaf spring and related front axle accessories, and ensures the stability of steering and braking performance of the whole vehicle. Every front axle I-beam undergoes strict dimensional inspection, ultrasonic flaw detection and load fatigue test before delivery to prevent bending, cracking and fracture under long-term heavy-load and complex road conditions. When the original beam is deformed or cracked, this spare part can be directly replaced. We maintain sufficient inventory and stable bulk supply for repair workshops, fleet operators, auto spare parts dealers and global cross-border export customers.
