199112340009/199012340068 Rear Wheel Hub With ABS

The 199112340009/199012340068 rear wheel hub with ABS is a core chassis component designed specifically for heavy-duty trucks like Sinotruk HOWO and Shaanxi Auto models. It integrates an ABS tone ring to monitor wheel speed and prevent brake lock-up, and adopts a full-floating axle structure-capable of independently supporting the vehicle's weight while stably transmitting power. Made of high-strength cast iron, it is compatible with both drum and disc brake systems, serving as a key part for ensuring driving safety and load-bearing performance of heavy trucks.

(1) ABS Safety Enhancement

Features an integrally cast ABS tone ring for stable signal transmission, preventing wheel lock-up during braking. This reduces skidding risks on rainy or slippery roads, boosting driving safety.

Complies with domestic heavy-truck braking standards and is compatible with mainstream ABS systems (e.g., WABCO).

(2) Durability & Load-Bearing Capacity

Supports a single-axle load of up to 13 tons, suitable for heavy-duty scenarios like engineering dump trucks and long-haul logistics. The cast iron material offers excellent impact resistance and wear resistance.

Undergoes anti-rust treatment on the surface, adapting to harsh working conditions such as muddy terrain and heavy rainfall.

(3) Easy Maintenance

Optional maintenance-free bearing version: No disassembly or inspection required for 3 years or 500,000 km, reducing downtime for repairs.

Bolt-on design: No need to disassemble the entire axle during replacement, enabling simple installation.

(4) Strong Compatibility

Directly fits mainstream models like HOWO T5G/T7H and Shaanxi Auto Delong M3000/X3000, requiring no additional modifications.

(1) Applicable Vehicle Models

HOWO series: Heavy trucks such as HOWO T5G, T7H, and TX7;

Shaanxi Auto series: Tractors and dump trucks like Shaanxi Auto Delong M3000, X3000, and L3000.

(2) Application Scenarios

Long-haul trunk logistics and port transportation (for high-mileage, stable driving needs);

Engineering construction and mining transportation (for heavy-load, complex road condition needs);

Hazardous material transportation (for scenarios with high requirements on braking safety).

Q1: How to verify the authenticity of this wheel hub?

A1: Check the original factory laser marking (199112340009/199012340068) on the hub flange, and query the part number in Sinotruk/Shaanxi Auto's official spare parts system. Also, inspect the surface for the original anti-counterfeiting label.

Q2: Can this ABS-equipped wheel hub be retrofitted to older heavy-truck models?

A2: It depends on whether the original axle head specifications (e.g., axle spline count, bolt hole position) match. It is recommended to consult the truck manufacturer's after-sales service first to avoid installation failures due to incompatible axle heads.

Q3: Does the ABS tone ring require separate maintenance?

A3: Daily maintenance only requires regular cleaning of dirt and iron filings on the tone ring surface to prevent signal interference. If an ABS alarm occurs, check for cracks or wear on the tone ring.

Q4: What is the tightening torque for the hub bolts?

A4: It is recommended to tighten the bolts to 380–400 N·m using a torque wrench, following a "diagonal sequence" for step-by-step tightening to avoid uneven stress.

Q5: What is the difference between the maintenance-free version and the standard version?

A5: The maintenance-free version uses sealed bearings and long-lasting grease, eliminating the need for regular grease refilling. For the standard version, it is recommended to check the bearing lubrication condition every 100,000 km and refill grease as needed.
