The GFB610 planetary gearbox is a high-torque reduction unit for hydraulic drive applications. The supplied technical data lists a rated output torque of 85,000 Nm, a maximum output torque of 127,500 Nm and multiple reduction ratios.
Hydraulic motor options are listed from several manufacturers. The appropriate configuration depends on the required output torque, reduction ratio, input speed, motor interface and equipment mounting requirements.
For replacement projects, confirm the complete model identification, mounting dimensions, shaft or spline connection and operating conditions before ordering.

This list does not establish that every motor model is interchangeable. Confirm motor displacement, mounting interface, shaft connection, hydraulic pressure and flow requirements for the target application.
Selecting a planetary gearbox requires more than matching the model number or maximum torque. The gearbox must be suitable for the equipment's actual load, speed, installation arrangement and operating cycle.
Output torque: Confirm the required rated torque and peak torque.
Reduction ratio: Select the ratio required to achieve the target output speed.
Input speed: Ensure the actual operating speed is within the specified limit for the selected configuration.
Hydraulic motor: Check displacement, mounting dimensions, shaft connection, pressure and flow.
Mechanical interfaces: Verify the housing dimensions, mounting holes and output connection using the relevant drawing.
Duty conditions: Consider load fluctuations, operating duration, temperature and other application-specific conditions.
If the gearbox is being considered as a replacement for an existing unit, compare the complete technical configuration rather than relying on a model-name match.
Provide the existing gearbox nameplate, model number, mounting drawing, output connection dimensions and hydraulic motor information to help assess compatibility.
Compatibility should be confirmed before describing the gearbox as a direct replacement or interchangeable unit.
The supplied specifications list a rated output torque of 85,000 Nm and a maximum output torque of 127,500 Nm. Confirm the applicable duty conditions and torque definitions in the final datasheet.
The supplied data lists single-stage ratios of 4.1, 5.2 and 6.3; two-stage ratios of 16.3, 21.2, 24.9, 27.3, 32.8 and 38.9; and three-stage ratios of 67.9, 88.3, 113.4, 136.3, 158.9 and 187.2.
The supplied technical table lists a maximum input speed of 3,500 r/min. Confirm the applicable limit for the selected gearbox and motor configuration.
The supplied information lists options from Danfoss, Eaton, M+S, Bosch Rexroth, Linde, SAM, Sauer, SAI, Dinamic Oil and Calzoni. Exact compatibility must be checked against the motor and gearbox interfaces.
Replacement suitability depends on the torque rating, gear ratio, mounting dimensions, output connection and motor configuration. Compare the technical drawings before confirming interchangeability.
Provide the gearbox model, required output torque, target speed, preferred ratio, motor information, mounting dimensions and application conditions.
