Product Description
I-MAK IR Series Gear Units
The I-MAK IR Series Gear Units are inline helical gearboxes designed for efficient industrial speed reduction and torque transmission. Moreover, their compact construction combines high mechanical performance with optimised installation dimensions.
The range includes single-stage and two-stage configurations. In addition, available models provide output speeds from 2.4 to 852 rpm.
Suitable configurations accept motor powers from 0.12 to 160 kW and deliver torque up to 18,000 Nm. Therefore, the IR Series suits both high-speed machinery and demanding low-speed, high-torque applications.
Single-Stage and Two-Stage Design
Single-stage units provide moderate speed reduction with high efficiency. Therefore, they suit equipment that requires relatively high output speeds.
Alternatively, two-stage configurations provide greater reduction ratios. As a result, they can deliver lower output speeds and increased torque.
Moreover, the broad combination of ratios allows engineers to match the gearbox with the actual machine duty. Consequently, users can avoid unnecessary external belts or additional reduction systems.
Robust Unicase Housing
The IR Series uses a rigid unicase housing. Therefore, the main bearing locations and gear supports remain integrated inside a single gearbox body.
This construction improves structural strength and supports accurate gear alignment. Moreover, the housing helps dissipate operating heat.
As a result, the gearbox can provide reliable performance under demanding loads. In addition, the compact casing simplifies installation where machine space is limited.

- IR 62–63–64: Up to 400 Nm; 35 mm shaft
- IR 721–731–741: Up to 600 Nm; 35 mm shaft
- IR 72–73–74: Up to 850 Nm; 40 mm shaft
- IR 82–83–84: Up to 1,440 Nm; 50 mm shaft
- IR 92–93–94: Up to 3,000 Nm; 60 mm shaft
- IR 102–103–104: Up to 4,300 Nm; 70 mm shaft
- IR 122–123–124: Up to 8,000 Nm; 90 mm shaft
- IR 142–143–144: Up to 13,000 Nm; 110 mm shaft
- IR 152–153–154: Up to 18,000 Nm; 120 mm shaft
Therefore, smaller models suit auxiliary equipment and lighter production machinery. In contrast, larger units support heavy conveyors, mixers and material-handling systems.
However, maximum torque depends on the selected ratio, motor power, operating hours and service factor. Consequently, users should complete a proper drive calculation before selecting the final unit.
High-Efficiency Helical Gears
Helical gear teeth engage gradually rather than making sudden full-width contact. Therefore, the gears transmit power smoothly.
Moreover, I-MAK uses precision-machined, case-hardened gears. As a result, the IR Series provides efficient transmission, reduced vibration and quiet operation.
Consequently, the gearbox suits indoor factories and production areas where excessive drive noise may be undesirable.
Flexible Input Options
Available input arrangements include:
- Helical gear unit without motor
- Gear unit with IEC motor adaptor
- Complete geared motor
- Gear unit with PAM-IEC motor arrangement
Therefore, users can purchase a complete motor-and-gearbox package or install a compatible IEC motor separately.
Moreover, an IEC-PAM adaptor can simplify future motor replacement. As a result, maintenance teams may service the drive without replacing the complete gearbox.
Mounting Configurations
Available arrangements include:
- Foot-mounted geared motor
- Flange-mounted geared motor
- Combined foot-and-flange geared motor
- IEC-PAM foot-mounted unit
- IEC-PAM flange-mounted unit
- Gearbox-only foot or flange models
Consequently, the IR Series integrates with many machine frames and installation layouts. Moreover, its modular design supports several thousand possible configurations.
High Radial-Load Capacity
Conveyors, pulleys and belt-driven machinery can apply substantial radial forces to the output shaft. Therefore, the gearbox must support more than output torque alone.
I-MAK identifies high radial-load support as a principal IR Series advantage. Consequently, the range suits conveyors, fans and other equipment with external shaft loads.
However, engineers must still verify the exact radial and axial forces for the selected model.
IR Series Applications in the UAE
The I-MAK IR Series may suit:
- Conveyor systems
- Industrial pumps
- Mixers and agitators
- Fans and ventilation equipment
- Packaging machinery
- Material-handling systems
- Food-processing equipment
- Textile machinery
- Manufacturing lines
- Water-treatment equipment
- Feeders and dosing systems
- General process machinery
For example, a conveyor can use an IR gearbox to reduce motor speed while increasing available torque. Similarly, a pump or fan system can use a compact inline unit where installation space is restricted.
Why Choose I-MAK IR Series Gear Units?
The IR Series combines high-efficiency helical gearing with a rigid unicase housing. Moreover, its broad torque, speed and mounting options support a wide range of industrial machines.
Therefore, it is a practical choice for UAE facilities that require compact installation, quiet operation, high radial-load capacity and dependable long-term performance.
