Description
EXA INDUSTRIAL PORTAL GEARBOX SYSTEM FOR GWM TANK 300
The EXA industrial portal gearbox system is the definitive drivetrain engineering solution for GWM Tank 300 platforms, designed to maximize operational ground clearance while maintaining powertrain integrity. For procurement departments serving the petrochemical and heavy industry sectors in Jubail Industrial City, Saudi Arabia, this system provides a critical 109 mm (4.3-inch) axle lift. This enables the deployment of 37 to 40-inch wheel configurations on technical support fleets without the traditional risks of axle failure. By utilizing hub-reduction technology with a 1.67:1 ratio, the system effectively unloads the factory differentials, significantly increasing the mean time between failures (MTBF) in the high-ambient, high-saline environments of the Eastern Province.
Direct B2B procurement through ChinaCar.pw facilitates a streamlined path for global special machinery sourcing, focusing on technical transparency and OEM-tier quality control. The EXA system is engineered for extreme thermal resilience, operating efficiently in temperatures up to +60°C. Each kit is supplied as a comprehensive conversion package including high-ventilation disc brakes and integrated Central Tire Inflation System (CTIS) connectivity. Our commitment to supply chain compliance ensures that every international export batch is accompanied by metallurgy affidavits and end-of-line dynamometer test logs, providing the technical assurance required for institutional fleet integration.
Technical Procurement & Compliance:
- Verified industrial banking gateways for secure B2B settlements between China and Saudi Arabian hubs.
- Strict technical alignment of financial flows with factory serial numbers and ISO 9001 quality standards.
- Risk mitigation via escrow-ready payment structures and multi-currency international trade frameworks.
- High-speed industrial logistics solutions to minimize downtime in infrastructure and petrochemical projects.
Technical Executive Summary:
Industrial EXA Portal Gearboxes for GWM Tank 300 platforms. Axle lift: 109 mm (4.3"). Drivetrain reduction: 1.67:1. Housing: Precision-cast Aluminum Alloy. Internal Components: Molybdenum-Titanium alloy gears. Features: Integrated CTIS support and performance disc brakes. Load Rating: 40 tonnes destructive resistance. Export ready for Jubail Industrial fleets.
The deployment of portal hub-reduction assets into the Jubail Industrial Hub requires absolute technical consistency with local SABIC or Aramco fleet standards. We provide direct sourcing for industrial drivetrain assets, ensuring that all gear tolerances are verified via Rockwell hardness testing. The integration of high-ventilation brakes prevents heat soak during prolonged technical maneuvers in extreme temperatures. Our global logistics handling includes reinforced export crating with vapor-phase corrosion inhibitors to protect precision alloy surfaces during ocean transit.
Maintaining the technical resilience of specialized off-road fleets involves a transition from standard lifts to portal hub reduction. We facilitate industrial component sourcing to ensure your procurement flow remains uninterrupted by localized supply chain gaps. Every EXA portal unit is engineered to keep CV axle operating angles within 5 degrees of factory settings, effectively eliminating the mechanical fatigue associated with extreme conventional lifts. Institutional clients can rely on our documented risk-free settlement protocols for high-value industrial drivetrain acquisitions.

Procurement managers often inquire: "What is the total landed cost for a professional hub-reduction portal system under CIF or DDP terms?". To facilitate institutional planning, we have developed a logistics estimator for industrial LCL cargo reaching the Port of Jubail. This calculation accounts for the journey from factory gates in the PRC to the final technical discharge at your regional hub. Utilizing direct maritime routes ensures a balanced approach between cost-efficiency and supply chain speed.
Logistics Estimator (Updated: January 2026)
Shipping Route: PRC Hub -> Shanghai Port -> Port of Jubail (KSA) -> Local Facility.
International Freight: from $1.55/kg (Industrial Promo Rate).
Regional Handling: Custom CIF / DDP options provided upon TDS finalization.
Note: Final landed cost is calculated strictly after technical documentation finalization. Pricing is subject to currency fluctuations, cargo density, and seasonal carrier surcharges.
Secure Global B2B / B2C Settlement Protocol
International transaction security in 2026 is maintained through the integration of verified industrial banking hubs, SWIFT settlement structures, and comprehensive trade compliance documentation. We utilize dedicated infrastructure for the procurement of high-value drivetrain systems for both corporate entities and individual professional buyers. This guarantees total legal transparency and protection against supply chain disruptions. Rigorous financial auditing ensures that all procurement flows meet global trade compliance and anti-money laundering standards.
"EXA portal systems represent the definitive hub-reduction solution for GWM platforms, essential for managing high-torque wheel loads in the arid industrial environments of Jubail. Only direct factory audits and ultrasonic casting verification ensure your fleet maintains peak operational readiness in Saudi Arabia."

Technical FAQ: Industrial Portal Sourcing
How much will the axle lift increase?
The EXA portal units provide a fixed axle lift of 109 mm. When paired with 37-inch industrial tires, the net ground clearance gain is approximately 150 mm.
Is a main differential gear swap required?
No. The 1.67 hub reduction ratio compensates for oversized wheels, effectively unloading the factory transmission and engine.
Is CTIS supported for Saudi fleets?
Yes, the industrial set includes technical preparation for central inflation hardware, allowing for on-the-fly pressure adjustment.
What is the gearbox industrial warranty?
The aluminum housings and alloy gears are covered by a 12-month industrial limited warranty for corporate procurement batches.
Do portals perform in extreme heat?
Units are verified for high-ambient operations up to +60°C. The aluminum alloy construction provides superior thermal dissipation.
Are international trade documents provided?
Yes. We supply a full documentation set, including Certificates of Origin and metallurgy affidavits for KSA customs clearance.
What wheel specifications are required?
A minimum wheel size of R17 with a positive offset (ET) of +30 or higher is required to house the portal unit inside the rim.
Is gear hardness verified during audit?
Absolutely. Technical audits include Rockwell hardness testing of the internal gear sets and ultrasonic casting verification.
