MAG-33VP-370E-1 Excavator Final Drive & MAG-33V Travel Motors

Product Overview: The MAG-33 Series is the global industry benchmark for travel drives in 3-to-5 ton class compact excavators. As a highly integrated hydrostatic propulsion unit, it seamlessly combines a high-pressure dual-speed piston motor with a multi-stage planetary gearbox. This selection features mainstream configurations: MAG-33VP-370E-1, MAG-33V-450-1, and MAG-33V-550. Renowned for superior gradeability and durability in muddy conditions, these units are widely compatible with brands such as Kubota, Yanmar, Bobcat, and IHI.

Key Technical Advantages:

• Automatic Dual-Speed Function: The MAG-33VP features automatic speed shifting, transitioning between “High Torque/Low Speed” and “Low Torque/High Speed” based on resistance to maximize productivity.

• Compact High-Pressure Design: The optimized swashplate piston architecture delivers massive tractive effort within a minimal footprint, ideal for space-constrained undercarriage layouts.

• Reinforced Planetary Gearing: Internal gears undergo high-frequency quenching for exceptional fatigue and shock resistance, ensuring stability during frequent counter-rotations.

• Premium Floating Seals: Utilizes industry-leading floating seal groups to exclude debris and moisture, significantly extending bearing and gear life.

• Plug-and-Play Installation: Standardized bolt patterns and port configurations (including Supply, Return, and Case Drain) ensure perfect OEM interchangeability and minimal downtime.

• Target Applications: 3-5 ton mini-excavator travel propulsion, crawler drills, and compact tracked chassis.
