Overview
Motovario BA42 7.62:1 bevel gearbox with a 20mm hollow bore output and 80B14 IEC motor input, configured for compact right-angle power transmission in machinery where reliable performance and efficient space use are both important.
This version is well suited to OEM equipment, compact production systems, and general industrial automation where a face-mounted motor arrangement is preferred. It offers dependable speed reduction, smooth mechanical operation, and a practical right-angle layout for installations with limited mounting space.
Low Reduction: Keeps output speed comparatively high while still increasing available torque, making it a strong option for transfer systems, packaging machines, light conveyors, and smaller driven assemblies.
The 20mm hollow bore output enables straightforward connection to smaller driven shafts, while the 80B14 IEC motor input supports compact face-mounted motor pairing for neat integration into modern machine builds. As part of the Motovario BA Series bevel gearbox range, it provides a modular and versatile drive solution for smaller industrial applications.

FAQ
Why use a 7.62:1 ratio on a compact bevel gearbox?
This reduction ratio is useful where machinery still needs reasonably fast shaft speed but also requires more turning force than direct drive can provide. It is a sensible option for equipment that needs controlled speed reduction without shifting into slower, higher-ratio performance.
When is the 80B14 motor input the better choice?
The 80B14 IEC input is often chosen where a compact face-mounted motor arrangement is required with an 80 frame motor. It suits applications where installation space, clean motor alignment, and straightforward flange mounting are important.
Configuration Notes
Input flange note: the 80B14 IEC motor input supports compact face-mounted motor installation, making it well suited to machinery where a neat mounting arrangement and efficient use of available space are priorities.
Output bore note: the 20mm hollow bore is designed for smaller shaft sizes, allowing secure engagement and practical installation in compact power transmission assemblies.
Application example: a good fit for compact conveyors, carton handling equipment, packaging systems, and automated machine stations where a small right-angle gearbox with relatively fast output speed and an 80B14 motor input is required.
