Overview
Motovario BA42 10.62:1 bevel gearbox with a 20mm hollow bore output and 71B14 IEC motor input, specified for smaller drive trains that need dependable right-angle transmission and straightforward motor integration.
This version is well suited to face-mounted machine builds, compact transfer units, and neatly packaged automation modules. The compact housing helps keep the drive train neat while still giving dependable mechanical performance in day-to-day industrial service.
Low Reduction: At 10.62:1, this configuration keeps output speed high for quicker-running driven components while still giving a worthwhile torque increase. In practical terms, that makes it best aligned with compact conveyors, indexing duties, small packaging stations, and light transfer systems.
Its 20mm hollow bore output suits smaller driven shafts and supports tidy mechanical integration in space-conscious machine layouts.
The 71B14 IEC motor input makes this version particularly suitable where a face-mounted motor arrangement is preferred for compact machine design and easy integration. Being part of the Motovario BA Series platform, it offers a proven modular solution for smaller industrial machines and replacement drive builds.

FAQ
Why choose a 10.62:1 reduction ratio?
This ratio is commonly selected for machinery that still needs fairly quick output rotation but also benefits from extra torque compared with direct drive. It is a good fit where the aim is to moderate speed rather than heavily reduce it.
Why choose the 71B14 motor input version?
The 71B14 input is useful where a smaller face-mounted motor connection is needed for a compact build. It helps suit tighter machine layouts and can be a better choice for equipment where installation footprint matters.
Configuration Notes
Input flange note: the 71B14 IEC motor input is intended for smaller motor frames using a compact face-mount arrangement, helping simplify integration into machinery with limited mounting space.
Output bore note: the 20mm hollow bore is suited to smaller driven shafts, giving secure shaft engagement and reliable transmission for compact drive systems.
Application example: suitable for small conveyors, product handling equipment, packaging machinery, and OEM automation assemblies where a compact right-angle gearbox is needed to combine efficient speed reduction with a space-saving motor connection.
