Why Choose the Skyond AZ4005415345 Bearing

1. Material That Matches OEM Standards

Manufactured from GCr15 bearing steel — the same material grade used in genuine Sinotruk steering components. This chromium-alloyed steel offers the optimal balance of hardness, wear resistance, and fatigue strength for heavy-duty truck applications.

2. Heat-Treated for Durability

High-frequency induction hardening is applied to the raceway surfaces, creating a hard wearing layer while retaining a tough core. This treatment resists pitting, spalling, and surface fatigue — common failure modes in steering bearings operating under high cyclic loads.

3. Precision-Ground for Smooth Operation

The rolling elements and raceways are precision-ground to minimize rotational friction. This results in lighter steering effort, reduced hydraulic pump load, and lower operating temperatures — contributing to longer steering system life.

4. Built for Harsh Conditions

Whether your HOWO 371 operates on long-haul highways, construction sites, or mining haul roads, Parts Steering Pressure Bearing is designed to handle vibration, shock loads, and contamination from dust and debris.

Application Scenarios

Long-Distance Freight

For fleets operating continuous highway routes, the bearing's low-friction design reduces steering system wear over hundreds of thousands of kilometers. Recommended inspection interval: 100,000 km under normal highway conditions.

Mining & Construction

In high-vibration, dust-heavy environments, the bearing's hardened raceways and tough core provide resistance to impact loads and abrasive wear. For severe-duty operations, we recommend inspecting the steering system every 50,000 km or 6 months.

Quality Assurance

· Raw Material: Each batch of GCr15 steel is verified with chemical composition analysis and hardness testing before production.

· Machining: CNC-controlled grinding ensures consistent dimensional accuracy across every batch.

· Outgoing Inspection: Each bearing undergoes rotation smoothness testing, dimensional verification, and visual inspection before packing.

· Traceability: Every bearing is marked with a batch code for production traceability.

Frequently Asked Questions

Q: Is AZ4005415345 a genuine Sinotruk part?

A: Parts steering pressure bearing is an OEM-equivalent replacement manufactured to meet or exceed Sinotruk's original specifications. It is not manufactured by Sinotruk, but is a high-quality aftermarket alternative designed for direct replacement.

Q: Will this bearing fit my HOWO 371?

A: Yes, this part is specifically engineered for the Sinotruk HOWO 371 with the HF9 front axle. It may also fit HOWO 336 and A7 models — please contact our team with your VIN or axle model to confirm compatibility.

Q: Is this belt compatible with other heavy-duty brands besides Howo?

A: Yes, it is designed for global compatibility with the 6PK1000 standard. If your vehicle uses a 1000mm length, 6-rib belt, this will fit. For verification, please provide your OE number.

Q: How does this compare to a "Genuine" dealer part?

A: Skyond belts are manufactured to match or exceed the performance parameters of original equipment. The primary difference is the cost-efficiency, as we pass the savings of streamlined manufacturing directly to the end-user.

Q: Can I install this without professional shop tools?

A: Yes. The high-flex design of our neoprene compound allows for manual installation by a skilled driver or fleet maintenance technician in roughly 20 minutes, making the Truck Belt Air Conditioning Belt the ideal choice for field repairs.
