Product Introduction

This fully integrated wheel hub bearing unit is a high-performance, maintenance-free solution for heavy-duty truck front wheel-ends. It eliminates the need for separate bearing installation and adjustment, while the integrated ABS ring ensures reliable wheel speed detection for the anti-lock braking system.

Structure & Material

• Material: High-strength forged steel (for the hub housing) and high-carbon chromium bearing steel (for the internal bearing). The ABS ring is made of spring steel with a corrosion-resistant finish.

• Design: A pre-assembled unit that includes the wheel hub, double-row tapered roller bearing, integrated ABS gear ring, and sealing system. The flange design enables direct wheel mounting, and the sealed construction prevents contamination.

Performance

• Integrated Functionality: Combines hub, bearing, and ABS speed sensing into one unit, simplifying installation and reducing maintenance.

• High Load Capacity: The double-row tapered bearing design supports heavy radial and axial loads from steering, braking, and vehicle weight.

• Contamination Protection: Multi-layer seals block dirt, water, and debris, ensuring long-term lubrication integrity and bearing life.

Durability

• Forged steel hub resists deformation under extreme loads and impacts.

• Sealed, pre-lubricated bearing design eliminates the need for re-greasing, extending service life.

• Corrosion-resistant coatings protect against road salt, moisture, and debris.

Core Function

1. Wheel Mount & Support: Provides a secure interface for the front wheel and bears the vehicle’s dynamic loads.

2. Integrated Bearing Operation: Delivers low-friction rotation and supports combined radial/axial forces.

3. ABS Speed Sensing: The integrated gear ring enables real-time wheel speed detection for anti-lock braking.

Frequently Asked Questions (FAQ)

What is the exact function of Wheel Hub Bearing Unit WG4071418068?

The WG4071418068 wheel hub bearing unit serves as the critical interface between the stationary front axle spindle and the rotating wheel hub. It allows the wheel to spin freely with minimal friction while supporting heavy radial loads (vehicle weight) and axial loads (cornering forces). Without a properly functioning bearing unit, wheel rotation becomes rough, heat builds up, and component failure follows quickly.

How do I confirm that WG4071418068 fits my specific Sitrak truck model?

The most reliable method is to cross-reference the OEM part number WG4071418068 against your vehicle’s parts catalog or VIN-based lookup system. If you’re unsure, simply send us your truck model, year, and axle configuration — our technical team will verify compatibility before you place an order. Reach out here for quick verification.

What are the signs that this wheel hub bearing unit needs replacement?

Common indicators include unusual humming or grinding noise from the wheel area, excessive play or wobble in the wheel when jacked up, uneven tire wear, and elevated hub temperature after driving. If any of these symptoms appear, inspecting and replacing the bearing unit promptly prevents cascading damage to the spindle, brake components, and wheel seal.

Is this bearing unit pre-greased and ready to install?

Yes. The WG4071418068 is supplied as a pre-assembled, pre-lubricated unit with factory-applied grease and integrated seals. This design eliminates the need for manual greasing during installation, reduces the risk of contamination, and ensures consistent lubrication from day one.

What quality assurance does Mettlead apply to this part?

Every Wheel Hub Bearing Unit WG4071418068 passes through a multi-stage inspection process: dimensional tolerance checks, surface hardness testing, seal integrity verification, and rotational noise assessment. We maintain OEM-equivalent standards across all production batches, so you receive consistent quality whether you order 10 units or 10,000.

Can I order a sample before committing to a bulk purchase?

Absolutely. We encourage new buyers to start with a sample order to evaluate fitment, finish quality, and packaging before scaling up. This approach builds trust and ensures the product meets your market’s expectations.
