Product Introduction

• Structure: A precision-forged integral steel half shaft with high-strength alloy steel material, surface carburizing and quenching hardening treatment, and precision-machined spline structures at both ends. The shaft body is designed with a lightweight hollow structure (partial section) and polished surface finish to reduce rotational resistance

• Performance: The high-hardness spline surface resists wear and shear force during torque transmission, and the integral forging process ensures the shaft body has excellent torsion and bending resistance, without deformation or fracture under heavy load. The polished surface and hollow design reduce the moment of inertia and improve the transmission response speed

Core Function

1. Transmission Torque Transfer: Precisely transmits the rotational torque of the transmission’s driving gear to the driven gear, realizing the power transmission and gear ratio conversion inside the gearbox

2. Spline Connection & Engagement: The high-precision splines at both ends form a rigid connection with the gear inner splines, ensuring no slip during torque transmission and maintaining stable power output

3. Heavy-Duty Load Bearing: The high-strength alloy steel and integral forging process can withstand the extreme torque and impact force generated by the engine during heavy load, start-up and gear shifting.

Application Scenario – Where Does This Half Shaft Fit?

The Half Shaft 711W35502-0149 is a critical drivetrain load-bearing component. More specifically, it sits between the rear axle differential and the wheel hub, transmitting rotational force to the drive wheels. Here’s where it belongs:

• Compatible Vehicles: Sinotruk Sitrak C7H, G7, T7H series heavy-duty trucks equipped with the corresponding rear drive axle assembly.
• Function: Torque transmission from the differential side gear to the wheel end, supporting full vehicle payload under acceleration, climbing, and braking conditions.
• Replacement Trigger: Typically required when spline wear causes play or vibration, or after axle overhaul and accident repair.

Because Sitrak trucks are widely deployed in mining, long-haul logistics, and construction haulage across emerging markets, demand for this half shaft remains consistently strong. Consequently, distributors who keep it in stock enjoy faster turnover and stronger customer loyalty.

Frequently Asked Questions – Half Shaft 711W35502-0149

What causes a half shaft to fail on Sinotruk Sitrak trucks?

The most common failure modes are spline wear due to prolonged overloading, fatigue cracking from repeated heavy braking on steep grades, and corrosion damage if the axle seal allows moisture ingress. Regular inspection during brake service helps catch early signs of wear before catastrophic failure occurs.

How can I verify that 711W35502-0149 fits my specific Sitrak model?

First, confirm your vehicle’s rear axle model number on the axle nameplate. Then cross-reference with the OEM part catalog. If you’re unsure, simply send us your truck’s VIN or axle tag photo, and our technical team will confirm compatibility within 24 hours.

Is this half shaft identical in quality to the original Sinotruk part?

Yes. We manufacture to OEM dimensional specifications using equivalent-grade alloy steel and the same heat-treatment process. Each unit passes hardness testing and spline gauge checks to ensure it performs identically to the factory-installed component.

What is the typical service life of this half shaft under normal conditions?

Under standard operating conditions (within rated payload, proper axle lubrication maintained), the Half Shaft 711W35502-0149 typically delivers 200,000–300,000 km of service. However, severe overloading or inadequate lubrication can significantly shorten its lifespan.

Can I order a sample before committing to bulk quantities?

Absolutely. We encourage new partners to order samples for dimensional verification and fitment testing. Once you’re confident in the quality, we’ll discuss tiered wholesale pricing based on your projected volumes.
