Overview
Motovario BA42 16.47:1 bevel gearbox with a 20mm hollow bore output and 80B14 IEC motor input, built for compact automation systems, light machinery, and general industrial duties where space is tight.
This version is well suited to compact production equipment, indexing stations, and machinery needing a face-mounted motor arrangement. This setup helps balance packaging size, installation practicality, and dependable drive performance in smaller industrial systems.
Low Reduction: At 16.47:1, this configuration sits at the upper end of the low-reduction group, giving more torque multiplication while preserving practical output speed. In practical terms, that makes it better suited to applications that need a little more pull, such as loaded conveyors, transfer systems, and harder-working OEM assemblies.
The 20mm hollow bore output gives a straightforward shaft-mount arrangement for smaller driven components, helping simplify installation and maintain reliable torque transfer.
With its 80B14 IEC motor input, this configuration suits compact machinery that wants a face-mounted motor format with a little more flexibility in motor matching. Being part of the Motovario BA Series platform, it offers a proven modular solution for smaller industrial machines and replacement drive builds.

FAQ
Why use a 16.47:1 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.
