Overview
Motovario BA52 51.34:1 bevel gearbox with a 25mm hollow bore output and 80B14 IEC motor input, built for compact right-angle power transmission in smaller industrial machines, conveyor assemblies, and OEM drive systems.
This configuration is a practical choice for compact machinery that needs more substantial speed reduction while keeping the overall gearbox assembly neat and space-efficient. It gives OEMs and maintenance teams a tidy way to introduce 90° power transmission without moving to an oversized gearbox assembly.
High Reduction: At 51.34:1, this version delivers significant speed reduction together with stronger torque multiplication. That makes it a strong fit for conveyors, packaging machinery, transfer equipment, and compact process systems where a slower, more controlled output speed is needed.
The 25mm hollow bore output gives a straightforward shaft-mount arrangement for smaller driven components, helping simplify installation and maintain reliable torque transfer.
The 80B14 IEC motor input suits applications needing a more substantial compact-face motor connection while still keeping the overall gearbox package compact. 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 51.34:1 reduction ratio?
A 51.34:1 ratio is a strong option when equipment needs significant speed reduction together with a useful increase in torque. It suits machinery that benefits from slower, more controlled output speed without stepping into the very highest reduction range.
What applications is this configuration suited to?
This configuration works well on conveyors, material handling systems, compact processing machinery, and automation equipment where a 25mm hollow bore and 80B14 motor input are needed.
Configuration Notes
Input flange note: the 80B14 IEC motor input uses a compact-face B14 flange arrangement with a 19 x 120 input dimension, 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: well suited to conveyors, handling systems, and industrial machinery where lower output speed, dependable torque transfer, and a 80B14 motor input are required.
