Overview
Motovario BA42 10.62:1 bevel gearbox with a 20mm hollow bore output and 80B5 IEC motor input, configured for compact right-angle power transmission in smaller industrial and OEM drive assemblies.
This version is well suited to slightly heavier compact machinery, conveyor sections, and bespoke OEM equipment using a B5 input. It offers an efficient way to handle right-angle speed reduction in machinery where every bit of mounting space counts.
Low Reduction: At 10.62:1, 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 20mm 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 makes this a good option where a larger B5 motor interface is required on compact conveyors, handling systems, and bespoke equipment. 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 10.62:1 ratio for this gearbox?
A 10.62:1 reduction ratio is useful where equipment still needs relatively quick shaft speed but also benefits from extra torque over direct drive. It is a practical choice for compact machinery that needs efficient speed control without heavy reduction.
Why use the 80B5 motor input version?
The 80B5 IEC input is typically chosen where a larger flange-mounted motor connection is required. It suits machinery that uses B5 flange motors as standard and benefits from direct mounting with secure alignment.
Configuration Notes
Input flange note: the 80B5 IEC motor input uses a larger flange mounting arrangement that supports direct motor coupling in compact industrial drive systems where secure installation and consistent alignment are important.
Output bore note: the 20mm hollow bore is intended for smaller shaft sizes, providing stable shaft engagement and practical integration into compact driven assemblies.
Application example: ideal for small conveyors, automated transfer systems, packaging machinery, and light-duty production equipment where a compact right-angle gearbox with an 80B5 motor input and relatively fast output speed is needed.
