Overview
Motovario BA52 31.63:1 bevel gearbox with a 25mm hollow bore output and 80B14 IEC motor input, configured for compact right-angle power transmission in smaller industrial and OEM drive assemblies.
This version is well suited to compact machinery, transfer drives, and lighter industrial systems where a slightly larger motor input is needed without moving to an oversized gearbox package. It gives machine builders and maintenance teams a practical way to achieve 90° power transmission while keeping the overall drive layout neat and efficient.
Medium Reduction: At 31.63:1, this version provides balanced speed reduction with a stronger torque increase. That makes it a strong fit for conveyors, packaging machinery, transfer equipment, and compact process systems where a steadier output speed and more substantial drive performance are needed.
The 25mm hollow bore output provides a straightforward shaft-mount arrangement for smaller driven components, helping simplify installation while maintaining dependable torque transfer.
The 80B14 IEC motor input is a strong option where a compact B14 flange arrangement is preferred but with compatibility for slightly larger motor pairings than smaller frame sizes. Being part of the Motovario BA Series platform, it offers a proven modular solution for compact industrial machinery and replacement drive builds.

FAQ
Why choose a 31.63:1 reduction ratio?
A 31.63:1 ratio is a strong option when machinery needs a balanced output speed together with a more noticeable torque increase. It suits applications that need more speed reduction than low-ratio gearboxes while still avoiding the very slow outputs associated with higher reduction levels.
What applications is this configuration suited to?
This gearbox is well suited to conveyors, packaging machinery, transfer drives, feeders, and OEM equipment where a 25mm hollow bore and 80B14 motor input are required.
Configuration Notes
Input flange note: the 80B14 IEC motor input uses a compact B14 flange arrangement with compatibility for slightly larger motor frames, making it suitable for tighter machine layouts where a more substantial motor mounting size is needed.
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: a good fit for conveyors, compact transfer systems, packaging equipment, and OEM machinery where a right-angle gearbox with balanced output speed and stronger torque gain plus a 80B14 motor input is needed.
