The GFB309 planetary swing drive gearbox is designed for hydraulic rotary transmission applications. The supplied technical data lists a rated output torque of 18,000 Nm, a maximum output torque of 24,000 Nm and multiple reduction ratios to support different equipment requirements.
The listed configuration supports several hydraulic motor options, including A2FM, A6VM, OMP, OMS and OMT series motors. Final selection depends on the required torque, gear ratio, motor interface, mounting dimensions and operating conditions.
For replacement projects, verify the existing gearbox model, mounting dimensions, output connection, hydraulic motor configuration and braking requirements before ordering.
The following table summarizes the supplied technical data for the GFB309 planetary gearbox. Confirm the exact configuration and operating limits against the approved technical datasheet before installation.

The listed output torque and brake torque are different parameters. Confirm their definitions, applicable operating conditions and the required braking configuration before selecting the gearbox.
The supplied specifications list hydraulic motor options from the A2FM, A6VM, OMP, OMS and OMT series. The compatible motor depends on the required output speed, hydraulic flow, operating pressure and gearbox interface.
A2FM series: Listed sizes 80, 107, 125, 160 and 180.
A6VM series: Listed sizes 80, 107 and 160.
OMP, OMS and OMT series: Additional listed hydraulic motor options, subject to configuration compatibility.
Confirm the complete motor model, displacement, shaft connection, mounting interface and hydraulic port arrangement before ordering. The listed motor families should not be treated as universally interchangeable.
Use the product drawing and the confirmed model-specific images to verify the gearbox configuration, mounting arrangement and connection interfaces before installation.
The supplied technical data lists a rated output torque of 18,000 Nm and a maximum output torque of 24,000 Nm. Confirm the allowable torque for the required duty cycle and selected gear ratio.
Single-stage, two-stage and three-stage ratio options are listed for the GFB309. The selected ratio affects output speed and the operating configuration, so it should be matched to the equipment requirements.
The gearbox is listed with several hydraulic motor options. Verify the motor displacement, input interface, operating pressure and oil flow to ensure that the selected motor and gearbox are compatible.
The supplied table lists a maximum brake torque of 850 Nm. Confirm the brake type, torque definition, release requirements and compatibility with the target equipment before use.
Planetary swing drives are used in equipment requiring controlled rotary movement and torque transmission. Depending on the selected configuration, potential applications include:
Excavator swing and rotary drive systems
Crane rotation and positioning mechanisms
Mobile machinery with hydraulic rotary drives
Special-purpose industrial equipment requiring high-torque rotation
Application suitability should be confirmed against the equipment manufacturer's torque, speed, mounting and duty-cycle requirements.
Before selecting a GFB309 gearbox, prepare the following information to help verify that the required configuration matches the application.
Output torque: Identify the required rated torque and peak torque.
Reduction ratio: Select the ratio required to achieve the target output speed.
Hydraulic motor: Confirm the motor model, displacement, mounting interface and hydraulic requirements.
Brake requirements: Check the required braking torque, release method and operating conditions.
Mounting dimensions: Compare the housing, bolt pattern, shaft or spline connection and installation clearance.
Operating duty: Consider load fluctuations, operating duration, temperature and the machine's working environment.
If the GFB309 is being considered as a replacement for an existing gearbox, do not rely on the model number or nominal torque alone. Differences in gear ratio, mounting dimensions, output connection, motor interface and brake configuration may affect compatibility.
Provide the original gearbox model, nameplate information, mounting drawing, output dimensions and hydraulic motor details for a compatibility review before ordering.
Use terms such as "replacement gearbox option" until the required mechanical and hydraulic interfaces have been verified. Do not claim direct interchangeability without supporting technical evidence.
Follow the manufacturer's installation, lubrication and maintenance instructions for the specific gearbox configuration. Maintenance intervals should reflect the operating conditions and duty cycle.
Check lubricant level and condition according to the manufacturer's instructions.
Inspect mounting fasteners and connections for looseness or visible damage.
Monitor operating temperature, vibration and abnormal noise.
Inspect seals and interfaces for signs of lubricant leakage.
Stop operation and investigate abnormal conditions before returning the unit to service.
The supplied technical data lists a rated output torque of 18,000 Nm and a maximum output torque of 24,000 Nm. Confirm the applicable operating conditions and torque definitions in the final datasheet.
The supplied data lists single-stage ratios of 4.2 and 5.3, two-stage ratios of 21.8, 28.2, 38.6 and 46.7, and three-stage ratios of 60.5, 80.6, 104.6 and 162.5.
The supplied data lists A2FM, A6VM, OMP, OMS and OMT series options. Confirm the exact motor model and connection interfaces for the selected configuration.
The supplied table lists a maximum brake torque of 850 Nm. Confirm the brake type and applicable operating limits in the technical documentation.
Replacement suitability depends on the torque rating, ratio, mounting dimensions, output connection, motor interface and brake configuration. Check the relevant technical drawings before confirming compatibility.
Provide the gearbox model, required torque, target output speed, preferred ratio, hydraulic motor details, mounting drawings and application conditions to support product selection.
