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 I-MAK IR gearbox range suits both high-speed machinery and demanding low-speed, high-torque applications.
Single-Stage and Two-Stage Gear Design
The I-MAK IR Series Gear Units are available with single-stage and two-stage reduction arrangements.
Single-stage units provide moderate speed reduction with high mechanical efficiency. Therefore, they suit equipment that requires relatively high output speeds.
Alternatively, two-stage IR gear units 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 I-MAK IR gearbox 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 I-MAK IR Series Gear Units can provide reliable performance under demanding loads. In addition, the compact casing simplifies installation where machine space is limited.

Therefore, smaller IR gearboxes suit auxiliary equipment and lighter production machinery. In contrast, larger models 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
The I-MAK IR Series Gear Units use helical gear teeth that engage gradually instead of 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 helical gearbox 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 for the I-MAK IR gearbox 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
The I-MAK IR Series Gear Units support several mounting arrangements, including:
- 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 numerous equipment 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 capacity as a principal advantage of the IR Series. Consequently, an I-MAK IR gear unit can suit conveyors, fans and other equipment with external shaft loads.
However, engineers must still verify the exact radial and axial forces for the selected model, ratio and shaft arrangement.
I-MAK IR Series Applications in India
The I-MAK IR Series Gear Units may suit many industrial applications across India, including:
- 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 gear unit where installation space is restricted.
Selecting the Correct I-MAK IR 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
- Shaft dimensions
- Radial and axial loading
- Ambient conditions
- Driven-equipment requirements
Therefore, users should calculate the required service factor before ordering an I-MAK IR gearbox. Otherwise, the gear unit may operate beyond its recommended mechanical capacity.
