Overview
Motovario BA52 14.63:1 bevel gearbox with a 25mm hollow bore output and 71B14 IEC motor input, configured for compact right-angle power transmission in smaller industrial and OEM drive assemblies.
This version is well suited to compact OEM drives, lighter conveyors, and smaller machine assemblies. It gives OEMs and maintenance teams a tidy way to introduce 90° power transmission without moving to an oversized gearbox assembly.
Low Reduction: At 14.63:1, 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.
The 25mm hollow bore output gives a straightforward shaft-mount arrangement for smaller driven components, helping simplify installation and maintain reliable torque transfer.
The 71B14 IEC motor input is ideal for compact motor pairings where a smaller flange format is preferred for tighter machine layouts and OEM integrations. 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 14.63:1 reduction ratio?
A 14.63:1 ratio is ideal where machinery needs a relatively fast output speed together with moderate torque increase. It suits equipment that benefits from controlled speed reduction without moving into medium or high reduction territory.
What applications is this configuration suited to?
This gearbox is a strong fit for compact conveyors, light-duty processing systems, packaging equipment, transfer drives, and OEM machinery where a 25mm hollow bore and 71B14 motor input are required.
Configuration Notes
Input flange note: the 71B14 IEC motor input uses a compact B14 flange format, making this gearbox particularly suitable for tighter machine layouts where smaller motor mounting dimensions are preferred.
Output bore note: the 25mm 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 smaller conveyors, transfer mechanisms, packaging systems, and automation equipment where a compact right-angle gearbox with relatively high output speed is needed.
