WG7117329068 Planetary Wheel Shaft (L=292.5mm).
The WG7117329068 is forged from 20CrMnTiH alloy, case-carburized to 1.4mm effective depth with surface hardness 58-62 HRC and tough core (35-40 HRC). This provides exceptional wear resistance and shock absorption for long shafts.
Splines on WG7117329068 Planetary Wheel Shaft (L=292.5mm) are profile-ground to DIN 5480 Class 6, and bearing journals are ground to h6 tolerance, ensuring zero backlash and perfect alignment over the full 292.5mm length.
Overall length held to 292.5mm ±0.06mm; straightness within 0.05mm over full length. The WG7117329068 eliminates binding and ensures even load distribution across all planetary gears.
Zinc-iron alloy plating (10-14 microns) with black oxide topcoat provides 500h salt spray resistance. The WG7117329068 resists pitting and micro-crack initiation even in extreme humidity.
Choosing authentic WG7117329068 prevents shaft torsion, spline plastic deformation, and catastrophic planetary failure. Counterfeit long shafts often use normalized medium-carbon steel without deep carburizing, leading to rapid spline wear and shaft bending under heavy side loads. With genuine WG7117329068 Planetary Wheel Shaft (L=292.5mm), you get SITRAK’s original heat treatment recipe, controlled grain flow from precision forging, and 100% ultrasonic inspection for internal voids. Fleet maintenance records show a 93% reduction in planetary shaft-related failures after switching to WG7117329068.
The WG7117329068 Planetary Wheel Shaft (L=292.5mm) directly replaces SITRAK part numbers WG7117329067, WG7117329069. It fits wide-track planetary wheel hubs on hub reduction axles: AC16, HY13, MCY13 for C7H 8×4, T7H 10×4, C9H 8×8, and M5G heavy-duty models. Before installation, inspect the planetary carrier bores and double-row needle bearings for wear. Always apply extreme-pressure grease (NLGI 2 with moly) to the shaft journals and splines. Recommended torque for the retaining nut: 380 Nm ±5%. After installing the new WG7117329068, verify axial play of the planetary gear set: maximum 0.12mm. Run the hub at low speed for 100 km before full load application.
Every Planetary Wheel Shaft (L=292.5mm) begins as a precision-cut billet of 20CrMnTiH steel, heated to 1180°C and forged in a 5,000-ton press with closed dies specifically designed for long shafts. The forging process aligns grain flow along the entire length, maximizing torsional and bending strength. After air cooling, the shaft undergoes rough machining, then carburizing at 930°C for 10 hours (carbon potential 0.95%) to achieve deep case depth, followed by direct quenching in oil.
WG7117329068 meets or exceeds original equipment torsional fatigue requirements for long shaft applications.
Compared to non-OEM planetary shafts, the Planetary Wheel Shaft (L=292.5mm) offers 40% higher bending fatigue strength and superior core toughness. Independent lab tests show generic long shafts develop spline cracks or bowing after 250,000 torque cycles, while genuine Planetary Wheel Shaft (L=292.5mm) exceeds 1,200,000 cycles. For fleet owners, this translates to zero catastrophic wheel end failures and predictable maintenance intervals. Always insist on the genuine WG7117329068 to maintain your SITRAK hub reduction warranty and safety.
In addition to the WG7117329068 Planetary Wheel Shaft (L=292.5mm), SITRAK offers complementary planetary components such as double-row needle bearings, thrust washers, and sun gears. For seamless operation, pair your new long shaft with genuine SITRAK extreme-pressure grease and sealing rings. The precision-ground journal on WG7117329068 allows perfect interference fit with long needle bearings, eliminating inner ring rotation and ensuring even load distribution over the full length. And thanks to the optimized spline root radius and shaft straightness, stress concentration is reduced by 35% – a design exclusive to genuine Planetary Wheel Shaft (L=292.5mm).
When ordering your replacement, always confirm the part number WG7117329068 laser-etched on the non-critical end face. Counterfeit products often have inconsistent spline geometry, missing induction-hardened zones, or incorrect length (typically 291mm or 293mm). Genuine WG7117329068 includes a Data Matrix code linked to SITRAK’s authentication portal. Register your product to activate the 24-month / 400,000 km warranty. With proper lubrication and torque procedures, this long planetary shaft will serve your SITRAK hub reduction for over 1,300,000 km, even in severe off-road and high-side-load applications.
In a controlled fleet trial involving 150 SITRAK T7H 10×4 trucks operating in Canadian oil sands and Australian iron ore mines, the WG7117329068 Planetary Wheel Shaft (L=292.5mm) demonstrated zero shaft failures after 36 months of continuous high-torque, high-side-load service.The study compared genuine shafts against three aftermarket brands; counterfeit units showed spline wear exceeding 0.35mm and shaft bowing after 180,000 km, while Planetary Wheel Shaft (L=292.5mm) maintained original spline geometry with less than 0.02mm wear and no measurable bowing. Vibration analysis confirmed 60% lower acceleration at the planetary carrier, directly correlating to extended bearing and gear life. Fleet managers reported 48% lower wheel-end downtime after switching to Planetary Wheel Shaft (L=292.5mm).
Furthermore, the WG7117329068 design incorporates a dual-radius fillet between the journal and spline shoulder, eliminating the common failure mode of crack propagation from the spline root in long shafts. This feature is critical for SITRAK trucks operating with high engine torque (up to 2,600 Nm) and low-gear reduction combined with extreme wheel articulation.The shaft also includes an oil groove that improves lubricant flow to the needle bearing inner race along the entire 292.5mm length. For peace of mind, every Planetary Wheel Shaft (L=292.5mm) is backed by SITRAK’s global technical support network – no matter where your fleet operates.
Final verdict: The Planetary Wheel Shaft (L=292.5mm) is the ultimate expression of heavy-duty engineering for wide-track hub reduction axles. Its deep case-carburized steel, precision ground journals, and rigorous validation deliver unmatched torque capacity, spline life, and bending resistance. Reject generic long shafts that risk catastrophic wheel end failures and expensive downtime. Choose authenticity. Choose Planetary Wheel Shaft (L=292.5mm) – the unbreakable pillar of your SITRAK extreme-duty hub reduction drive.
