The RE1022 swing drive motor is a compact hydraulic drive and planetary reduction unit designed to provide controlled rotary motion for mobile and industrial machinery. It combines a hydraulic motor with a reduction gearbox to convert hydraulic power into high-torque output for swing and rotary applications.
The RE1022 is suitable for equipment where controlled rotation, torque transmission, compact installation and reliable drive integration are important. Typical applications can include excavators, cranes, drilling equipment and other machinery requiring a hydraulic swing drive or rotary drive system.
The standard specification listed below provides a 9,000 N·m rated output torque, 10,000 N·m maximum output torque and a 36.1 reduction ratio. Final compatibility should be confirmed according to the machine's hydraulic circuit, mounting interface, operating cycle and torque requirements.
The RE1022 reducer uses a planetary reduction structure to provide speed reduction and torque multiplication within a compact housing. Planetary gearing is commonly used in mobile machinery because multiple gears can share the transmitted load while maintaining a relatively compact drive package.
When integrated with a hydraulic motor, the reducer converts the motor's input speed and torque into the output characteristics required by the machine's swing mechanism. The appropriate motor and reduction configuration should be selected according to the required output torque, speed, hydraulic pressure and flow.
The following specification describes the available RE1022 swing drive configuration. Actual machine performance depends on hydraulic-system conditions, installation configuration and operating duty cycle.
| Model | Rated Output Torque (N·m) | Maximum Output Torque (N·m) | Ratio | Compatible Motor | Maximum Brake Torque (N·m) | Reference / Replacement Models |
|---|---|---|---|---|---|---|
| RE1022 | 9,000 | 10,000 | 36.1 | OMP160, OMP200, OMP250, OMS160, OMS200, OMS250 | 650 | Dinamic Oil RE1022; Brevini ED2090; COMER PG1002 |
With a rated output torque of 9,000 N·m and maximum output torque of 10,000 N·m, the RE1022 is designed for applications requiring substantial rotary torque within a compact drive assembly.
The planetary gearbox provides a 36.1 reduction ratio, allowing the hydraulic motor's higher input speed to be converted into a lower-speed, higher-torque output suitable for rotary machinery functions.
The listed configuration is compatible with OMP160, OMP200, OMP250, OMS160, OMS200 and OMS250 hydraulic motors. Motor selection should be verified against the machine's available hydraulic pressure, flow and required output characteristics.
The RE1022 specification includes a maximum brake torque of 650 N·m. Brake selection and holding performance should be evaluated together with machine load, inertia, operating speed and safety requirements.
Combining the hydraulic motor interface and planetary reduction unit into one drive assembly can simplify installation and system integration where packaging space is limited.
The reducer is designed around a planetary gear architecture for transmitting torque through multiple gear elements. This configuration is widely used in heavy-duty motion systems where torque density and controlled output speed are important.
The reducer housing provides the structural interface between the hydraulic motor and the driven machine assembly. Before installation, mounting dimensions, shaft or flange interfaces, available clearance and bolt patterns should be checked against the target equipment.
Proper lubrication is important for planetary gears and bearings. Maintenance intervals should be established according to operating hours, load conditions, lubricant specifications, ambient environment and the manufacturer's service recommendations.
The RE1022 can be considered for mobile and industrial machinery requiring hydraulic rotary drive and torque multiplication. Application suitability should be confirmed from the machine's actual torque, speed, hydraulic and mounting requirements.

The RE1022 is listed with reference or replacement models including Dinamic Oil RE1022, Brevini ED2090 and COMER PG1002. Cross-reference suitability should always be verified using dimensional drawings, torque requirements, hydraulic specifications and mounting interfaces before replacement.
Selecting a suitable swing drive requires matching the drive to the complete machine system. Buyers and OEM engineers should review the following parameters before ordering:
Required output torque: Confirm rated and peak torque requirements for the machine.
Required swing speed: Determine the desired output rotational speed.
Hydraulic motor: Confirm motor displacement and compatibility with the available hydraulic circuit.
Hydraulic pressure and flow: Provide the operating pressure and pump flow available to the drive motor.
Brake requirements: Determine the required holding and braking torque.
Mounting dimensions: Check flange, shaft, bolt pattern and installation envelope.
Operating environment: Consider temperature, dust, moisture, vibration, shock and maintenance conditions.
For OEM and replacement projects, the swing drive should be selected according to actual machine interfaces and performance requirements rather than by model number alone. Kemer can evaluate application information such as torque, speed, motor type, pressure, flow and mounting dimensions when discussing a suitable configuration.
Customers requesting a quotation should provide, where available:

Required swing speed
Hydraulic motor model or displacement
Hydraulic operating pressure
Available oil flow
Brake requirements
Mounting drawings or dimensions
Any special operating or environmental requirements
