Product Introduction

This heavy-duty wheel hub flange is a critical wheel-end component, designed to provide a rigid interface for mounting the brake drum and wheel rim. Its integrated wheel studs ensure secure wheel attachment, while the precision-machined hub interface maintains alignment and load distribution.

Structure & Material

• Material: High-strength cast iron (for the flange body) and alloy steel (for the wheel studs), chosen for load-bearing capacity and impact resistance.

• Design: A one-piece cast flange with integrated, threaded wheel studs (gold zinc-plated for corrosion resistance) and a precision-machined central hub interface. The flange features a bolt pattern for brake drum attachment.

Performance

• Secure Wheel Mounting: The integrated studs and precision bolt pattern ensure a tight, vibration-resistant connection for the wheel and brake drum.

• Load Distribution: Distributes vehicle weight and dynamic loads evenly across the wheel hub and axle assembly.

• Torque Transfer: Transmits rotational torque from the hub to the wheel rim, enabling acceleration and braking forces to be applied effectively.

Durability

• Cast iron construction resists deformation under heavy loads and brake-induced thermal stress.

• Zinc-plated studs resist corrosion from road salt and moisture, maintaining thread integrity over time.

Core Function

1. Wheel & Brake Drum Mounting: Provides a secure interface for attaching the front wheel rim and brake drum.

2. Load Distribution: Distributes vehicle weight and dynamic loads to the wheel hub and axle.

3. Torque Transmission: Transfers rotational forces for acceleration and braking.

• Precise OEM Fitment – Manufactured to match the original Sinotruk Sitrak dimensional tolerances, ensuring a bolt-on installation with no modifications needed.
• High Torque Transmission – The flange face and bolt pattern are designed to handle the heavy torque loads typical of Sitrak’s drivetrain and axle assemblies.
• Superior Material Strength – Forged from high-grade steel alloy, heat-treated for hardness and fatigue resistance under continuous heavy-duty operation.
• Corrosion-Resistant Surface – Treated with a protective finish that resists rust and environmental degradation, extending service life in harsh operating conditions.
• Reduced Downtime – Direct replacement design means faster repairs, getting trucks back on the road sooner and protecting your bottom line.
• Strict Quality Control – Every batch undergoes dimensional inspection and material testing before shipment, so you receive parts that perform from day one.

In other words, this flange is built to work as hard as your Sitrak truck does — day after day, load after load.

Application Scenario: Where Does Flange AZ4071418040 Fit?

Understanding exactly where this part belongs helps you order with confidence. Here’s how the Flange AZ4071418040 Sinotruk Sitrak functions within the vehicle system:

• Compatible Vehicle – Sinotruk Sitrak heavy-duty truck series
• Component Type – Flange (法兰盘)
• Primary Function – Connects and secures mating components within the drivetrain or axle assembly
• Mechanical Role – Transmits torque between joined parts while maintaining precise alignment under load
• System Location – Typically installed at connection points in the front axle or transmission output assemblies

Because this flange serves as a critical junction point, using a substandard replacement can lead to vibration, misalignment, or even catastrophic failure. That’s why sourcing an OEM-spec part like the AZ4071418040 matters for long-term reliability.
