Overview
The Transtecno ITB helical bevel cast iron gearmotor range is designed for heavy duty industrial applications where strength, torque capacity and flexible installation options matter. As part of the Transtecno IRON range, the ITB series provides a robust right angle gearmotor solution for Australian businesses that need reliable power transmission in demanding machinery environments.
The helical bevel design makes the ITB range well suited to applications where the drive needs to transmit power through a right angle layout. This is useful when machinery space is limited or when the motor position needs to be arranged away from the driven shaft. Combined with a cast iron housing and modular input and output options, the ITB series is a strong choice for conveyors, process equipment, materials handling systems and heavy industrial machinery.
Motordrives Australia supplies and supports the ITB range for industrial users, machine builders and maintenance teams across Australia. Our team can assist with size selection, ratio selection, mounting position, output shaft style and motor compatibility for new installations or replacement projects.
Key Features
The ITB range is built with a robust cast iron housing for applications exposed to heavier mechanical loads and industrial working conditions. This construction helps provide the strength and rigidity required for machinery that needs dependable performance over long service periods.
The series includes three sizes: ITB 423, ITB 433 and ITB 443. These sizes offer respective torque capacities of 950 Nm, 1800 Nm and 3500 Nm, giving businesses a practical selection range for different load and speed requirements.
The ITB series has a high degree of modularity, with multiple input and output arrangements available. Catalogue versions include U, F…D and F…S gearbox versions, along with standard hollow output shaft arrangements, shrink disc options and torque arm configurations. This flexibility helps simplify integration into machinery where shaft position, mounting method and available space are important.
ITB gearmotors are supplied with synthetic oil lubrication, with oil quantity determined by the selected mounting position. Available mounting positions include M1, M2, M3, M4, M5 and M6. Correct mounting position should be confirmed before ordering to ensure the gearbox is supplied and installed to suit the operating orientation.
The gearmotors are finished with epoxy powder coating in RAL 7016, with an average thickness of 0.10 to 0.15 mm. The motor can be coupled by flexible coupling or motor sleeve depending on the chosen configuration.
Common Applications
ITB helical bevel cast iron gearmotors are suited to industrial applications where a right angle drive arrangement is preferred. Common uses include conveyors, bulk handling systems, mixers, production lines, packaging equipment, processing machinery and OEM equipment builds.
For Australian operators in mining, agriculture, food and beverage, water treatment, manufacturing and materials handling, the ITB series provides a practical way to combine heavy duty torque capacity with a compact right angle layout. This can be especially useful where machinery footprints are tight or where the motor needs to sit parallel with the driven equipment rather than directly in line.
The ITB range can also suit replacement projects where an existing right angle gearmotor needs to be matched against shaft size, mounting orientation, output speed and torque requirements. Motordrives Australia can help review the existing nameplate or application details to support a suitable replacement recommendation.
Selection Considerations
Selecting the right ITB gearmotor requires more than matching the maximum torque rating. The correct unit should be selected based on output speed, reduction ratio, motor power, service factor, radial load, mounting position, shaft arrangement and the real operating conditions of the equipment.
The ITB technical data includes input speed, output speed, reduction ratio, nominal input power, output torque, service factor and permitted radial loads. Service factor should be selected according to the application, including operating hours, load type, starts per hour and whether the drive will be exposed to shock loading.
Mounting position is important because lubrication quantity changes depending on orientation. The ITB series includes oil quantity data for M1, M2, M3, M4, M5 and M6 positions, so the selected gearbox should be confirmed against how it will actually sit on the machine.
Output radial load should also be checked carefully, especially where chains, belts, sprockets or pulleys are involved. The ITB series includes maximum output radial load ratings up to 18500 N for ITB 423, 23000 N for ITB 433 and 31000 N for ITB 443, but the final allowable load depends on the selected model, shaft arrangement and load position.
Accessory options can also affect the final specification. Torque arm kits, shrink disc output shaft kits, output shaft assembly kits, output shaft disassembly kits and backstop devices are available for selected configurations. The backstop device allows one way output shaft rotation and should be specified with the required rotation direction.
Support And Enquiries
Motordrives Australia can help select an ITB helical bevel cast iron gearmotor for new machinery, replacement drives and industrial upgrade projects. If you know your required output speed, motor power, reduction ratio, mounting position or existing gearbox model, our team can use that information to narrow down the correct configuration.
For the most accurate recommendation, include details such as the driven equipment, load type, duty cycle, shaft arrangement, available space, environmental conditions and any existing gearbox information. This helps ensure the selected ITB gearmotor is suited to the actual operating demands of your equipment.
