Product Introduction

• Structure: Integral precision-forged high-strength alloy steel shaft body, with double-end high-precision involute spline structures, surface adopts carburizing + quenching + tempering composite heat treatment, overall polished surface finish, and reinforced shaft shoulder design at the stress concentration position. The spline tooth surface is precision ground to ensure meshing accuracy, and the shaft body has no welds for integral structural strength

• Performance: The high-hardness spline surface (HRC58-62) resists severe wear and shear force during high-torque transmission; the integral forging and reinforced shaft shoulder design ensure excellent torsion and bending resistance, avoiding deformation or fracture under full-load start and heavy hauling conditions; the precision ground splines realize zero-clearance meshing, reducing gear meshing noise and vibration

Core Function

1. High-Torque Power Transmission: Transmits the rotational torque of the transmission’s driving gear to the driven gear stably and efficiently, matching the heavy-duty working condition demand of the vehicle, realizing reliable power conversion and output inside the gearbox

2. Precision Spline Meshing: The high-precision ground splines at both ends form a rigid and tight connection with the inner splines of the mating gears, eliminating meshing clearance, avoiding slip and tooth beating during torque transmission, and ensuring stable power output.

In addition, every batch goes through strict quality control inspections before shipment, so you can confidently guarantee consistent part quality to your downstream buyers.

Technical Specifications – Half Shaft 811W35502-0146 Sinotruk Sitrak

Accurate specifications are essential when sourcing drivetrain components for heavy-duty trucks. Below you will find the detailed parameters for this half shaft:

Application Scenario: Where Half Shaft 811W35502-0146 Performs

This half shaft is purpose-built as a drivetrain load-bearing component for the Sinotruk Sitrak platform. It sits within the rear axle assembly, transferring rotational force from the differential housing outward to the drive wheel hub. In practical terms, it is the link that keeps your truck moving forward under full payload.

Typical application scenarios include:

• Long-Haul Logistics: Sitrak C7H tractors covering thousands of kilometers monthly require half shafts that resist fatigue and maintain dimensional stability over time.
• Construction and Mining Haul: Heavy payloads and uneven terrain create extreme torsional stress — this component is built to absorb it.
• Municipal and Port Transport: Stop-and-go cycles increase stress frequency on drivetrain parts, making durability a non-negotiable quality.

Compatible Vehicle Platform: This half shaft directly fits Sinotruk Sitrak models equipped with rear axle assemblies calling for part number 811W35502-0146. Always cross-reference with your vehicle VIN or axle model number to confirm fitment before ordering in bulk.

Frequently Asked Questions – Half Shaft 811W35502-0146

What trucks does the Half Shaft 811W35502-0146 fit?

This half shaft is designed specifically for Sinotruk Sitrak heavy-duty truck models that use the 811W35502-0146 part number in their rear axle assembly. Common compatible models include the Sitrak C7H and G7 series. However, always verify against your axle BOM or VIN data before placing bulk orders, as axle configurations can vary by production year and market region.

What material is this half shaft made from, and how does it handle heavy loads?

It is forged from high-strength alloy steel and then heat-treated to improve hardness and fatigue resistance. This combination allows the shaft to handle the extreme torsional forces generated during full-load acceleration, hill climbing, and braking in heavy-duty applications — exactly the conditions Sitrak trucks face daily.

How can I tell if a half shaft needs replacement?

Common signs include unusual vibration or clunking noises from the rear axle area, uneven tire wear on drive wheels, or visible twisting, cracks, or spline damage upon inspection. In fleet maintenance, periodic visual inspections during brake or differential servicing help catch issues before catastrophic failure occurs on the road.

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

Yes. It is manufactured to OEM-equivalent specifications — same material grade, same dimensional tolerances, and same surface treatment processes. Every production batch undergoes strict quality control testing, including dimensional verification and hardness testing, to ensure it meets or exceeds original equipment standards.

What is the minimum order quantity for wholesale buyers?

MOQ depends on your order volume and packaging requirements. Mettlead works flexibly with distributors — whether you need a sample order for quality evaluation or large-volume container shipments. Contact our sales team to discuss pricing tiers based on your specific quantity needs.
