Product Introduction

This integrated wheel hub bearing assembly is a core wheel-end component, designed to support the vehicle’s weight and absorb dynamic loads during acceleration, braking, and cornering. It features pre-installed seals for maintenance-free operation.

Structure & Material

• Material: High-carbon chromium bearing steel, heat-treated for high hardness and wear resistance. Seals are made of nitrile rubber (NBR) for oil resistance.

• Design: A double-row tapered roller bearing with an integrated housing and pre-installed oil seals. The tapered design efficiently handles both radial and axial loads, while the sealed construction prevents contamination.

Performance

• Load Handling: The double-row tapered design supports heavy radial loads and axial thrust from braking/steering.

• Low Friction: Precision-machined components minimize friction, reducing heat buildup and extending service life.

• Contamination Protection: Integrated seals block dirt, water, and debris, ensuring long-term lubrication integrity.

Durability

• Bearing steel construction resists fatigue and wear under continuous heavy loads.

• Sealed design eliminates the need for re-greasing, reducing maintenance intervals.

Core Function

1. Wheel Hub Support: Bears the vehicle’s weight and dynamic operating loads.

2. Load Distribution: Efficiently transfers radial and axial forces to the axle/hub assembly.

3. Contamination Resistance: Sealed design maintains lubrication and protects internal components.

Frequently Asked Questions About Wheel Hub Bearing 812W93420-6097

What trucks does the 812W93420-6097 wheel hub bearing fit?

This bearing is specifically designed for Sinotruk Sitrak heavy-duty trucks. It installs in the rear axle wheel hub assembly and matches the original equipment dimensions and load ratings. If you’re unsure about compatibility with a particular Sitrak model variant, our technical team can confirm fitment before you order.

How can I tell if my wheel hub bearing needs replacement?

Common signs include unusual humming or grinding noises from the wheel area, excessive play or wobble in the wheel when jacked up, uneven tire wear, and elevated hub temperature after driving. If you notice any of these symptoms, inspecting and replacing the bearing promptly prevents more costly damage to the spindle or hub.

Is this bearing identical to the original Sitrak factory-installed part?

Yes. The 812W93420-6097 is manufactured to OEM-equivalent specifications, meaning it matches the original part in dimensions, material grade, hardness, and load capacity. It’s a direct drop-in replacement that requires no modifications during installation.

What material is used in this wheel hub bearing?

It’s made from GCr15 high-carbon chromium bearing steel, which is the industry standard for heavy-duty automotive bearings. This material offers excellent fatigue resistance, high hardness (HRC 60–65), and strong corrosion resistance — all essential for bearings operating under heavy loads and harsh conditions.

How should I store wheel hub bearings before installation?

Store them in a dry, clean environment away from direct sunlight and moisture. Keep the original packaging sealed until you’re ready to install. Avoid stacking heavy items on top of bearing boxes, as deformation of the packaging could expose the bearing to contaminants. Proper storage preserves the factory-applied grease and prevents surface corrosion.

Can I order this bearing in large quantities with custom packaging?

Absolutely. Mettlead supports bulk orders with white-label or custom-branded packaging. We can print your logo, part numbers, and market-specific labels on the box. Contact us with your volume requirements and branding specifications for a tailored quote.
