Product Description
Rexroth GFT Series Planetary Travel Drive Gearboxes
Product Overview: The Rexroth GFT Series (HYDROTRAC) is a high-performance planetary gearbox specifically engineered for tracked or wheeled mobile machinery. This drive assembly integrates multi-stage planetary gearing with a hydraulic motor interface to provide massive tractive effort in extreme environments. This selection features the complete spectrum from compact GFT36 to heavy-duty GFT110, GFT160, and GFT220, with a focus on core model GFT80W3B77-09 and OEM part number R988016174. With its space-saving design and high torque output, the GFT series is the premier choice for excavators, drill rigs, pavers, and cranes.
Key Technical Advantages:
Compact Planetary Gearing: Utilizing 2-stage or 3-stage planetary structures, these drives achieve massive reduction ratios and torque output within a minimal envelope, optimizing chassis layouts.
Integrated Solutions: The gearbox features an integrated multi-disc parking brake and is designed for direct mounting of Rexroth A2FE or A6VE plug-in hydraulic motors.
Superior Load Capacity: Robust heavy-duty bearing systems are designed to handle significant radial and axial forces directly from tracks or wheels.
