Overview
Motovario BA42 14.46:1 bevel gearbox with a 20mm hollow bore output and 80B14 IEC motor input, specified for smaller drive trains that need dependable right-angle transmission and straightforward motor integration.
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 14.46:1, this configuration introduces a slightly deeper speed drop than the entry low ratios while remaining fast enough for responsive machine movement. In practical terms, that makes it a strong option for general conveying, product handling, assembly equipment, and compact production machinery.
Its 20mm hollow bore output suits smaller driven shafts and supports tidy mechanical integration in space-conscious machine layouts.
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 14.46:1 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.
