Product Introduction

This integrated rear wheel hub is a core wheel-end component, designed to support the vehicle’s weight, transfer torque to the wheel, and provide a stable mounting surface for the brake drum. It comes pre-assembled with bearings and an O-ring seal for simplified installation and maintenance.

Performance

• High Load Capacity: The ductile iron construction and integrated bearings support the full weight of the truck and its dynamic loads from acceleration, braking, and cornering.

• Precision Alignment: The splined interface ensures accurate alignment with the axle shaft, while the precision bearing bore maintains optimal wheel positioning.

• Contamination Protection: The integrated O-ring seal blocks dirt, water, and debris from entering the axle connection, preserving lubrication and extending component life.

Durability

• Ductile cast iron resists deformation and fatigue under continuous heavy loads and thermal stress from braking.

• The sealed bearing and O-ring design maintain lubrication integrity, reducing maintenance needs and extending service life.

• Zinc-plated studs resist corrosion, maintaining thread integrity over time.

Core Function

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

2. Load Support: Bears the vehicle’s weight and dynamic operating loads.

3. Torque Transfer: Transmits rotational power from the axle shaft to the wheel.

Application Scenario: Where Does This Rear Wheel Hub Fit?

The Rear Wheel Hub 812-35700-6130 is specifically designed for the following application:

• Compatible Vehicle: Sinotruk Sitrak heavy-duty trucks (C7H, G7, and related series)
• Installation Position: Rear axle — mounts directly to the axle spindle
• Primary Function: Supports and carries the rear wheels, integrating braking components (brake drum, ABS ring) and drivetrain elements (axle shaft flange connection)
• Working Environment: Long-haul logistics, mining transport, construction site haulage, and any application where sustained heavy loads are the norm

Frequently Asked Questions About Rear Wheel Hub 812-35700-6130

What trucks does the 812-35700-6130 rear wheel hub fit?

This rear wheel hub is designed specifically for Sinotruk Sitrak heavy-duty trucks, including the C7H and G7 series. It mounts on the rear axle and is compatible with the standard 10-stud wheel configuration used across these models. If you are unsure about fitment, simply send us your vehicle’s VIN or axle model number, and we will confirm compatibility.

Is this rear wheel hub an original part or aftermarket?

The 812-35700-6130 is manufactured to OEM-equivalent specifications. This means it matches the original Sinotruk dimensions, material standards, and performance characteristics. You get the same reliability as a factory-installed part, but at a more competitive price point because we supply directly from our production facility.

How does the rear wheel hub integrate with braking components?

The hub is machined with precise mounting surfaces for the brake drum and ABS sensor ring. When installed correctly, it ensures proper alignment between the brake shoes and drum, which is critical for even braking force distribution. Additionally, the hub’s bearing seat maintains the correct axial and radial tolerances needed for smooth wheel rotation under braking loads.

What causes a rear wheel hub to fail, and how can I prevent it?

The most common causes of rear wheel hub failure include overloading beyond rated capacity, improper bearing preload during installation, and lack of lubrication maintenance. To extend service life, always torque wheel nuts to the manufacturer’s specification, inspect bearings during routine maintenance intervals, and replace seals if you notice any grease leakage.

Can I order this rear wheel hub with custom packaging for my brand?

Absolutely. Mettleda offers white-label and custom packaging services. You can specify your brand name, logo, part number format, and barcode requirements. This is particularly useful for distributors and aftermarket retailers who want to maintain brand consistency across their product lines.

What is the typical lead time for bulk orders?

Lead time depends on order quantity and current stock levels. For standard quantities, we typically ship within 7–15 business days. Larger custom orders may require 20–30 days for production. We recommend contacting our sales team early to lock in your delivery schedule.
