Product Description

SINOTRUK HOWO AC16 Heavy Duty Truck AZ9981320139 Inter-Axle Differential Cross Spider Shaft


This heavy-duty truck wheel-end and differential reducer component is a premium side half shaft gear precision-engineered for heavy commercial transport axles. Featuring an optimized involute tooth profile, it meshes smoothly with planet gears within the rear differential assembly to deliver seamless power split to the axle shafts. This transmission component safeguards heavy-load vehicles against rotational binding and catastrophic gear tooth shearing during sharp turns, heavy-torque starts, or steep climbs. Engineered to withstand continuous multi-directional stress and severe driveline shocks, this side gear ensures consistent, high-efficiency mechanical torque transfer, helping fleet operators sustain maximum uptime and driveline safety across demanding transport corridors.

Product Specification


Product Name Rear Half Shaft Gear
Part Number  AZ9981320166

Origin China
Quality Standard 100% Tested
Quality Certification ISO, CCC, GSO, CE, SGS, TUV
Weight 1.85 KG
Dimensions

Precision Profile Involute & Safety Upgrade: Engineered with a precision-forged involute tooth profile, this side half shaft gear ensures an optimized contact pattern and uniform load distribution across meshing gear teeth. It eliminates concentrated stress points during sudden torque spikes, providing smooth differential operation that prevents sudden gear fracturing or axle lockups on high-speed freight routes.
20CrMnTi Alloy & Carburized Durability: Manufactured from premium 20CrMnTi heavy-duty gear steel and treated with an advanced multi-purpose furnace carburizing process, the gear features a diamond-hard exterior shell with an ultra-tough shock-absorbing core. This dual-metallurgical structure delivers superb anti-pitting resistance, extending operational life cycles and minimizing rear axle overhaul intervals.

All-Weather Resilience & Thermal Resistance: Engineered to maintain absolute dimensional stability under severe friction-induced heat, this gear prevents thermal deformation during continuous high-load operations. It guarantees reliable, smooth power transmission in harsh environmental extremes, from mud-clogged mining operations and dusty construction tracks to freezing cross-border logistics corridors.

100% OEM Alignment & Direct Replacement: Crafted strictly according to factory AC16 axle master blueprints, this side gear matches internal spline counts, pitch diameters, and thrust washer interfaces exactly. Driveline mechanics can execute a seamless, drop-in replacement without differential box machining, lowering vehicle downtime and cutting fleet repair labor expenses.


Fine Grinding Optimization & Drivetrain Silence: Undergoing a specialized CNC micro-grinding finish, the gear faces exhibit ultra-low surface roughness that dampens backlash fluctuations and low-frequency chassis chattering. By eliminating gear play and knocking noises within the rear axle housing, it optimizes drivetrain stability and enhances driver handling comfort.

اشتريتُ قبل ثلاثة أسابيع حشوات زيت متينة لشاحنات أسطولي من شركة HOWO من هذا المتجر المستقل. بصفتي مدير أسطول أدير 22 شاحنة نقل بضائع في لاغوس، كنتُ بحاجة إلى حشوات مطاطية متينة تتحمل درجات الحرارة العالية على الطرق الأفريقية الوعرة. كل حشوة تناسب تمامًا دون أي تسريب للزيت أثناء النقل لمسافات طويلة. استغرقت الشحنة إلى ميناء لاغوس 8 أيام فقط، وكان فريق المبيعات سريع الاستجابة عندما طلبتُ أسعار الجملة.
