Gear shaft sun pinion 7521-2405260-20 for Belaz 75131/75306 electric mining dump truck

In the mining industry, the performance of dump trucks is paramount, and high-quality Belaz spare parts are at the core of that performance. Our parts are precision-engineered for exceptional durability, capable of withstanding the most extreme mining conditions — from scorching heat to freezing cold as low as -50°C — to ensure smooth and efficient operation.

1. Engine Components
From cylinder blocks and cylinder heads to pistons, connecting rods, crankshafts and fuel injection systems, every engine component is manufactured to the strictest OEM standards. Whether you need parts for YaMZ, Cummins, DEUTZ, MTU or other engine configurations, we deliver reliable power and fuel efficiency even under continuous heavy loads.

2. Transmission Parts
Our transmission components — including gearboxes, torque converters, drive shafts, differentials, and planetary hub drives — ensure seamless power delivery and exceptional wear resistance. We supply parts for both hydromechanical transmissions (5+2, 3+1, 6+1 gear ranges) and AC/DC electromechanical transmission systems.

3. Robust Chassis Elements
Frames, suspensions (air-hydraulic cylinders with built-in shock absorbers), axles (both front and driving axles), brake systems (shoe brakes, dry disk brakes, multiple-disk oil-cooled brakes), steering components, wheel hubs, and tire assemblies — all are reinforced to endure severe shock and high stress, providing a solid foundation that extends the service life of your trucks.

4. Hydraulic System Components
Hydraulic pumps, cylinders (dump hoists, steering cylinders, suspension cylinders), control valves, hoses, and seals — all manufactured to ensure reliable lifting and dumping operations under the most demanding conditions.

5. Electrical & Electronic Components
Alternators (GSN-500, GST-1, SGT-1000), traction motors (EDP-600, EK-590, TED-6, ED-136, EK-420A), control modules, sensors, wiring harnesses, and battery assemblies for both conventional and electric drive systems.

6. Body & Wear Parts
Dump bodies (struck volumes from 15.1 m³ to 103.8 m³, heaped 2:1 volumes up to 134.8 m³), liners, wear plates, tailgates, canopy cabs, and operator protection structures.

By choosing our Belaz mining dump truck parts, you can significantly reduce downtime. Reliable quality means fewer breakdowns and lower maintenance costs — the comprehensive annual savings from reduced operating costs, lower maintenance expenses, and improved productivity can be substantial. We understand the importance of uninterrupted mining operations. Our parts are here to make that possible.
