Overview
Motovario BA52 62.58:1 bevel gearbox with a 25mm hollow bore output and 80B5 IEC motor input, designed for efficient 90° power transmission in compact machinery, automated equipment, and smaller industrial drive systems.
It gives machine builders and maintenance teams a dependable way to achieve very low output speeds and substantial torque increase in space-conscious drive layouts. It gives OEMs and maintenance teams a tidy way to introduce 90° power transmission without moving to an oversized gearbox assembly.
Very High Reduction: At 62.58:1, this version produces very slow output speed together with maximum torque multiplication. That makes it a strong fit for conveyors, transfer equipment, indexing systems, and compact process machinery where highly controlled slow-running performance is required.
The 25mm hollow bore output gives a straightforward shaft-mount arrangement for smaller driven components, helping simplify installation and maintain reliable torque transfer.
The 80B5 IEC motor input is suited to applications needing a larger B5 flange motor connection, giving broader motor compatibility and a more substantial input-side arrangement for compact machinery builds. 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 62.58:1 reduction ratio?
A 62.58:1 ratio is a strong option when equipment needs very slow output speed together with maximum torque multiplication. It suits machinery that benefits from substantial speed reduction while keeping drive performance controlled and dependable.
What applications is this configuration suited to?
It is well suited to packaging systems, transfer equipment, slower-running process lines, and general industrial machinery that need a 25mm hollow bore together with a 80B5 motor input.
Configuration Notes
Input flange note: the 80B5 IEC motor input uses a 19 x 200 mounting dimension and a larger B5 flange arrangement, making it suitable for applications that need a dependable motor connection while still keeping a compact right-angle gearbox format.
Output bore note: the 25mm hollow bore is designed for smaller driven shafts, providing secure shaft engagement and dependable torque transmission in lighter-duty and general industrial applications.
Application example: ideal for packaging machinery, transfer drives, and automation equipment where very slow speed and a 80B5 motor input are part of the drive specification.
