Overview
The Transtecno ITH helical in-line cast iron gearmotor range is designed for industrial applications where the drive unit is expected to handle heavy loads, continuous operation and demanding site conditions. With a robust cast iron housing and a modular gearmotor design, the ITH range suits Australian businesses that need reliable power transmission for production equipment, conveyors, processing lines and heavy machinery.
The in-line helical layout is well suited to applications where the motor and output shaft need to remain coaxial. This makes the ITH series a practical option for machine builders, plant operators and maintenance teams that require a strong, compact and serviceable drive solution without unnecessary complexity.
Motordrives Australia supplies and supports the ITH range for industrial users across Australia, helping customers select the correct size, ratio, motor arrangement and mounting configuration for their operating requirements.
Key Features
The ITH range is built around a cast iron housing, giving the gearbox the strength and rigidity required for heavier duty applications. This makes it suitable for machinery exposed to high mechanical loads, regular start-stop cycles and industrial operating environments where lighter duty gear units may not be appropriate.
The series is available across ITH 112/3, ITH 122/3, ITH 132/3 and ITH 142/3 sizes, with respective transmittable torque ratings of 700 Nm, 1000 Nm, 1800 Nm and 3500 Nm. This allows the gearmotor to be selected according to the load, speed and duty requirements of the machine.
A high degree of modularity is a key advantage of the ITH system. Different input and output kits can be configured to suit the application, helping simplify integration into both new machinery and replacement projects. The catalogue includes U, F, U/F and G versions, along with multiple IEC motor adapter options depending on the selected gearbox size.
ITH gearmotors are supplied with synthetic oil lubrication, with oil quantity determined by the mounting position. Available mounting positions include M1, M2, M3, M4, M5 and M6, giving engineers and installers flexibility when designing around available space, shaft orientation and machine layout.
The units are finished with epoxy powder coating in RAL 7016, with an average thickness of 0.10 to 0.15 mm. Motor connection is achieved via flexible coupling or motor sleeve, depending on the selected configuration.
Common Applications
ITH helical in-line cast iron gearmotors are suited to applications where durability, torque capacity and modular configuration are important. Common uses include industrial conveyors, mixers, processing equipment, materials handling systems, packaging machinery, bulk handling equipment and general manufacturing plant.
For Australian operators in mining, agriculture, food processing, water treatment, manufacturing and OEM machinery, the ITH range provides a strong gearmotor platform that can be matched to a broad range of working conditions. The in-line shaft arrangement is particularly useful where equipment layout calls for direct, coaxial power transmission.
The optional backstop device is available for applications where the output shaft must rotate in one direction only. This can be useful in selected conveyor and lifting related applications where reverse movement needs to be controlled, subject to correct engineering selection.
Selection Considerations
Selecting the correct ITH gearmotor depends on more than choosing a torque figure. The right configuration should take into account output speed, reduction ratio, motor power, service factor, radial loads, mounting position, shaft arrangement and operating environment.
The ITH catalogue includes detailed technical data for input speed, output speed, reduction ratio, input power, output torque, service factor and permitted radial loads. Service factor must be selected according to the actual application, including operating hours, load characteristics, starts per hour and any shock loading.
Mounting position is also important because the lubrication quantity changes depending on orientation. Before specifying the gearmotor, confirm whether the application requires M1, M2, M3, M4, M5 or M6 mounting so the correct oil quantity and breather arrangement can be considered.
For applications with sprockets, pulleys or overhung loads, radial load capacity should be checked carefully. The ITH range includes output radial load ratings up to 8200 N, 12500 N, 18500 N or 22500 N depending on gearbox size, but the final allowable load depends on the selected model and load position.
Support And Enquiries
Motordrives Australia can assist with selecting an ITH helical in-line cast iron gearmotor for new installations, replacement units and machinery upgrade projects. If you already have a gearbox model, motor size, ratio or application details, our team can help review the required configuration.
For the most accurate recommendation, include details such as required output speed, load type, motor power, duty cycle, mounting position, shaft arrangement and environmental conditions. This helps ensure the selected ITH gearmotor is suited to the real operating demands of your equipment.
