Overview
Motovario B153 14.01:1 bevel gearbox with a 90mm hollow bore output and 200B5 IEC motor input, designed for efficient 90° right-angle drive integration in demanding industrial power transmission applications.
Engineered for dependable daily operation, it delivers stable speed reduction and reliable torque transfer for OEM machinery, plant equipment, and continuous-duty processing systems.
Low Reduction: Ideal for applications that require relatively higher output speed while still benefiting from practical torque multiplication, making it well suited to conveyors, packaging lines, transfer systems, and light-to-medium duty automation.
This configuration combines a 90mm hollow output bore with a 200B5 IEC motor input, creating a robust drive package for larger motor pairings where secure shaft engagement and consistent power transmission are essential.
With its 200B5 flange input, this version is intended for larger IEC motor frames, increasing motor compatibility and input-side capacity while maintaining a compact right-angle installation layout and dependable industrial performance.
As part of the modular Motovario B Series bevel helical gearbox range, this unit supports flexible mounting arrangements, straightforward IEC motor fitment, and proven long-term service in continuous industrial environments.

Ratio Selection Tips
Best for: faster-running right-angle drive applications that still need dependable torque increase, including conveyor systems, packaging equipment, feeders, and automated material handling lines.
Selection tip: a 14.01:1 ratio is a good fit when you want to retain relatively high output speed while improving torque transmission and overall driveline efficiency. It works particularly well in continuously operating machinery where compact layout, smooth operation, and stable performance are important. Always check startup load, inertia, and duty cycle before final selection.
FAQ
Is 14.01:1 suitable for applications that need quicker output speed?
Yes — this ratio is well suited to machinery that needs higher output speed than mid or high reduction setups while still gaining practical torque multiplication. If your application needs very slow output speed or maximum reduction, a higher ratio would usually be more appropriate.
Can this gearbox run with a VFD-controlled motor?
Yes — it can be paired with an inverter-controlled motor for more precise speed adjustment and smoother machine performance. For prolonged low-speed running, make sure the motor has adequate cooling and is correctly sized for the application.
Configuration Notes
Input flange note: the 200B5 IEC input is designed for larger motor frames, making this version suitable for applications that require increased motor capacity and stronger input-side drive performance.
Output bore note: the 90mm hollow bore is intended for larger driven shafts, providing a secure and stable mechanical connection for dependable torque transmission in demanding industrial assemblies.
Application example: ideal for conveyors, packaging transfer systems, or automated handling lines where a compact right-angle drive, larger motor compatibility, and relatively fast output speed are required.
