Product Description
I-MAK IRS Series Gear Units
The I-MAK IRS Series Gear Units are cast-iron worm gearboxes designed for simple industrial applications that require high reduction ratios. Moreover, their compact right-angle construction reduces motor speed while increasing output torque.
The official range supports ratios from approximately 7.5:1 to 111:1. In addition, suitable configurations accept motor powers from 0.12 to 22 kW.
Therefore, the IRS Series suits conveyors, mixers, feeders and industrial machinery that require controlled low-speed operation.
Reliable Worm-Gear Operation
The worm shaft drives a larger worm wheel inside the gearbox. Consequently, the arrangement provides substantial speed reduction within a compact housing.
The input and output shafts operate at right angles. Therefore, machine designers can use the gearbox where an inline drive arrangement would require too much space.
Moreover, the worm-drive design provides smooth power transmission. As a result, the IRS Series offers low vibration during suitable operating conditions.

Available IRS Models
The official IRS range includes:
- IRS 52: Up to 240 Nm; 20 mm shaft
- IRS 65: Up to 415 Nm; 25 mm shaft
- IRS 82: Up to 825 Nm; 30 mm shaft
- IRS 102: Up to 1,465 Nm; 40 mm shaft
- IRS 127: Up to 2,650 Nm; 50 mm shaft
- IRS 162: Up to 4,820 Nm; 70 mm shaft
- IRS 201: Up to 7,200 Nm; 80 mm shaft
- IRS 250: Up to 12,500 Nm; 90 mm shaft
Therefore, smaller models suit light machinery and auxiliary drives. In contrast, larger units support heavier conveyors, mixers and manufacturing equipment.
However, maximum torque depends on ratio, motor power, service factor and operating conditions. Consequently, users should complete a proper drive calculation before selecting a model.
High Ratios and Low Output Speeds
Many industrial machines require slower movement than a standard electric motor can provide. Therefore, the IRS Series offers high reduction ratios for controlled low-speed operation.
For example, a conveyor can use the gearbox to reduce belt speed while increasing available drive torque. Similarly, a mixer can use a high-ratio unit for slower and more controlled agitation.
Moreover, the gearbox removes the need for additional belts or external reduction stages. As a result, the complete drive arrangement can remain compact.
Strong Cast-Iron Housing
The IRS Series uses a robust cast-iron housing. Therefore, the gearbox provides strong mechanical support for the gears, shafts and bearings.
In addition, the rigid construction helps maintain gear alignment under suitable industrial loads. Consequently, the unit can provide reliable service in demanding production environments.
However, installers must still provide a stable mounting surface. Moreover, they should avoid excessive shaft, belt or coupling loads.
Backstop Protection
A backstop can prevent the gearbox output from rotating in an unwanted reverse direction.
Therefore, it can support inclined conveyors, lifting equipment and other systems where reverse movement may create a process or safety concern.
However, the required rotation direction must be specified before ordering. Consequently, the motor must not operate against the permitted backstop direction.
Moreover, users should confirm backstop availability for the exact IRS model, ratio and mounting configuration.
Input and Mounting Options
Available configurations include:
- IRSAM: Foot-mounted geared motor
- IRSFM: Flange-mounted geared motor
- IRSA: Foot-mounted gearbox
- IRSF: Flange-mounted gearbox
- IRSAP: IEC-PAM foot-mounted gearbox
- IRSFP: IEC-PAM flange-mounted gearbox
Therefore, users can select a complete motor-and-gearbox package or connect a compatible IEC motor separately.
Moreover, multiple mounting positions simplify installation on different machinery layouts.
IRS Series Applications in the UAE
The I-MAK IRS Series may suit:
- Conveyor systems
- Industrial mixers
- Screw feeders
- Packaging machinery
- Manufacturing equipment
- Material-handling systems
- Food-processing machinery
- Textile equipment
- Water-treatment equipment
- Automated production lines
- Small lifting mechanisms
- General process machinery
For example, an inclined conveyor can use a backstop-equipped unit to help prevent unwanted reverse travel. Similarly, a feeder can use a high-ratio IRS gearbox for controlled material delivery.
Selecting the Correct IRS Gear Unit
Correct selection depends on:
- Motor power and input speed
- Required output speed
- Required output torque
- Reduction ratio
- Daily operating hours
- Starting frequency
- Shock and reversing loads
- Mounting position
- Backstop requirement
- Shaft and flange dimensions
Therefore, users should calculate the required service factor before ordering. Otherwise, the gearbox may operate beyond its recommended capacity.
