The replacement of NBPG NB400T Series track drives planetary gearbox is a specialized gear speed reducer for tracked vehicles and earth-moving machines. The reduction gearbox has a heavy-duty casing, a short overall length, and great radial and axial load capacity.
Our gearboxes are provided with an integral multi-disc parking brake and have been designed for the direct mounting of hydraulic plug-in motors. The careful selection of the materials and design allows our gear reducers to be used in even the most severe environments. The replacement of NB400T Series gearboxes is the perfect transmission solution for crawler undercarriages, drilling, crushing, screening, and piling machines.
1. Output torque range: 1000-450000N.m
2. Gear ratios: i=5.3-500
3. Support: the gearbox has rotating housing flanges to fit tracks
4. Applicable motors: axial piston hydraulic motors, hydraulic orbit motors, or others
5. Hydraulic motor options: pressure relief valve, over-center valve
6. Bearing: robust bearing system absorbing the forces exerted by the ring gear
7. Brake: hydraulic released parking brake
8. High torque and load capacities: to carry equipment over the roughest and steepest terrain.
9. Designed to allow mounting of plug-in motors.
10. Integral multi-disc parking brakes, while still keeping the drive compact.
11. Steel structure.
12. Easy maintenance: filling and draining openings are reasonably located for easy reach.
13. Front mechanical seal designed specifically for the earth-moving machines.
14. Technical data and installation dimension of NB400T Series gearbox are the same as those of Rexroth GFT…T Series and Bonfiglioli 700C Series, so these 3 can be used interchangeably.
