Product Description
I-MAK IRK Series Gear Units
The I-MAK IRK Series Gear Units are helical-bevel gearboxes designed for efficient industrial speed reduction and torque transmission. Moreover, their right-angle construction supports compact machinery layouts where installation space is limited.
The range accepts motor powers from 0.12 to 200 kW. In addition, available configurations provide output speeds from 0.17 to 214 rpm.
Therefore, the IRK Series suits both moderate-speed machinery and demanding low-speed, high-torque applications.
Efficient Helical-Bevel Gear Design
The gearbox combines helical gears with a bevel gear stage. Consequently, it transfers power through a right-angle drive while maintaining high mechanical efficiency.
Helical gear teeth engage gradually during operation. Therefore, they support smooth torque transmission and reduce operating noise.
Meanwhile, the bevel stage changes the direction of power between the motor and output shaft. As a result, the gearbox fits efficiently into compact machine layouts.
Key Benefits of the IRK Series
- Helical-bevel gear construction
- High mechanical efficiency
- Compact, space-saving design
- Quiet and smooth operation

Together, these features provide dependable power transmission for many industrial duties. Moreover, the broad model range allows users to match speed, torque and shaft dimensions with the driven equipment.
Available IRK Models
The official IRK range includes:
- IRK 42–43: Up to 180 Nm
- IRK 52–53: Up to 220 Nm
- IRK 63: Up to 400 Nm
- IRK 73–74: Up to 780 Nm
- IRK 83–84: Up to 1,330 Nm
- IRK 93–94: Up to 2,572 Nm
- IRK 103–104: Up to 4,010 Nm
- IRK 123–124: Up to 8,000 Nm
- IRK 142–144: Up to 13,000 Nm
- IRK 153–154: Up to 18,000 Nm
Therefore, smaller models suit auxiliary machinery and lighter conveyors. In contrast, larger configurations support heavy mixers, production lines and material-handling systems.
However, maximum permitted torque depends on ratio, motor power, operating hours and service factor. Consequently, users should complete a proper drive calculation before selecting the final model.
Low-Speed and High-Torque Operation
Some industrial equipment requires substantial torque at a controlled low speed. Therefore, the IRK range provides output speeds down to approximately 0.17 rpm.
For example, low-speed configurations can drive industrial mixers, rotary tables and slow-moving conveyors. Moreover, the multistage reduction eliminates the need for additional belts or external reduction equipment.
As a result, the complete drive system can remain compact and easier to maintain.
Flexible Shaft Options
The IRK Series supports several output arrangements, including:
- Solid output shaft
- Hollow output shaft
- Double output shaft
- Shrink-disc connection
- Multiple flange configurations
Therefore, users can select a connection that matches the driven shaft and machine structure.
For example, a hollow-shaft unit can connect directly to the machine shaft. Alternatively, a shrink-disc arrangement can provide a secure, keyless connection.
Input and Mounting Configurations
Available input options include:
- Input shaft without motor
- IEC-PAM flange without motor
- Complete gearbox with motor
- IEC-PAM flange with motor
Meanwhile, standard arrangements include:
- IRKM: Foot-mounted geared motor
- IRKFM: Flange-mounted geared motor
- IRKPM: IEC-PAM foot-mounted geared motor
- IRKFPM: IEC-PAM flange-mounted geared motor
- IRK: Foot-mounted gearbox
- IRKF: Flange-mounted gearbox
- IRKP: IEC-PAM foot-mounted gearbox
- IRKFP: IEC-PAM flange-mounted gearbox
Consequently, engineers can adapt the gearbox to different machine frames and motor preferences.
Quiet and Low-Maintenance Performance
The precision gear design supports smooth tooth engagement. Therefore, the gearbox produces less noise and vibration during correct operation.
Moreover, high-efficiency gearing reduces internal power losses and unnecessary heat generation. As a result, the IRK Series supports reliable operation and lower energy demand.
However, low maintenance does not mean maintenance-free. Consequently, users should follow I-MAK guidance for lubricant checks, seal inspection, alignment and operating-temperature monitoring.
I-MAK IRK Applications in the UAE
The IRK Series may suit:
- Conveyor systems
- Industrial mixers and agitators
- Material-handling machinery
- Packaging equipment
- Food-processing systems
- Manufacturing lines
- Water-treatment equipment
- Textile machinery
- Rotary tables
- Crushers and feeders
- Automated production equipment
- General process machinery
For example, a conveyor can use the right-angle design to reduce installation length. Similarly, a mixer can use a high-ratio model for controlled low-speed agitation.
Selecting the Correct IRK Gear Unit
Correct selection depends on:
- Motor power and input speed
- Required output speed
- Required output torque
- Daily operating hours
- Starting frequency
- Shock and reversing loads
- Mounting position
- Shaft configuration
- Ambient temperature
- Driven-machine requirements
Therefore, users should calculate the required service factor before ordering. Otherwise, the gearbox may operate beyond its recommended capacity.
