Wheel Hub Bearing Unit WG4071418068 Sinotruk Sitrak

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.
