SY335 Excavator Final Drive & Travel Motor – MAG-18000VP & MAG-85VP Series

Product Overview: Engineered for SY335 and similar heavy-duty 30-ton plus excavators, we provide OEM-standard travel drive solutions. This featured selection includes industry-leading models: MAG-18000VP-6000, MAG-33VP-370E-1, MAG-85VP-1800-9, and the MAG18V travel motor assembly. Combining a high-pressure dual-speed piston motor with a multi-stage planetary gearbox, these assemblies are designed to deliver superior tractive effort and unmatched durability in extreme environments such as mines, quarries, and large-scale earthmoving projects.

Key Technical Advantages:

• Heavy-Duty Traction: The MAG-18000VP is optimized for 30-40 ton class equipment, providing massive torque to ensure the machine maintains power in muddy or steep-sloped terrains.

• Automatic Dual-Speed Shifting: Integrated variable displacement control allows smooth transitions between “High Torque/Low Speed” and “Low Torque/High Speed” based on load resistance, optimizing fuel efficiency.

• Reinforced Planetary Gearbox: Internal gears are forged from high-strength alloy steel and deep-hardened to withstand massive shock loads from frequent counter-rotation and rough terrain.

• Extreme Sealing Protection: Equipped with premium floating seal groups to effectively exclude mud, water, and abrasive debris, significantly extending bearing service life.

• OEM-Grade Compatibility: Standardized bolt patterns and port configurations ensure a perfect fit for SY335 and other mainstream models, allowing for zero-error interchangeability.

• Target Applications: Heavy excavator travel drive replacement, mining machinery undercarriage maintenance, and heavy-duty tracked platforms.
