Overview
Motovario BA42 22.97:1 bevel gearbox with a 20mm hollow bore output and 80B14 IEC motor input, built for neatly packaged right-angle drive systems where a face-mounted IEC motor input and steady output speed are required in compact machine assemblies.
This configuration is well suited to applications that need efficient 90° drive transfer, dependable mechanical performance, and a compact gearbox layout for smaller machine builds and automation assemblies.
Medium Reduction: This entry medium reduction ratio keeps a useful running speed while adding a clear step-up in torque, making it a strong option for general conveyors, packaging stations, transfer systems, and continuous-duty automation.
The 20mm hollow bore output provides a secure and practical fit for smaller driven shafts, helping ensure stable torque transmission and straightforward mechanical integration.
Equipped with a 80B14 IEC motor input, this version is intended for face-mounted motor builds needing a slightly larger motor pairing while keeping the gearbox footprint compact. As part of the Motovario BA Series bevel gearbox platform, it offers a modular solution for space-conscious industrial applications.

FAQ
Why choose a 22.97:1 reduction ratio?
A 22.97:1 ratio sits at the quicker end of the medium-reduction range, making it ideal where machinery needs a noticeable speed drop and stronger torque output without becoming slow-running.
What applications is this configuration suited to?
This gearbox is a strong fit for production modules, indexing units, face-mounted compact machinery, and transfer equipment where a 20mm hollow bore and 80B14 motor input are required.
Configuration Notes
Input flange note: the 80B14 IEC motor input is designed for face-mounted motor builds needing a slightly larger motor pairing while keeping the gearbox footprint compact, making this gearbox suitable for compact drive assemblies where space efficiency and simple motor matching are important.
Output bore note: the 20mm hollow bore is intended for smaller driven shafts, providing secure shaft engagement and dependable torque transfer in lighter-duty and general industrial applications.
Application example: well suited to compact conveyors, packaging lines, transfer systems, and general automation equipment where a medium reduction ratio with relatively lively output speed is preferred.
