Overview
Motovario B163 58.97:1 bevel gearbox with a 100mm hollow bore output and 180B5 IEC motor input, designed for robust right-angle power transmission in industrial machinery where reliable reduction performance and a compact installation layout are both important.
This configuration is built for demanding OEM and plant environments, delivering dependable speed reduction, smooth mechanical operation, and consistent torque transfer across continuous-duty applications.
High Reduction: This ratio provides lower output speed with stronger torque multiplication, making it ideal for conveyors, mixers, feeders, indexing systems, and heavier-duty industrial machinery.
The 100mm hollow output bore makes this version well suited to larger shaft-driven assemblies, helping provide secure shaft engagement and stable power transmission in heavier-duty installations.
With its 180B5 IEC motor input, this unit is intended for use with larger flange-mounted motors, giving added flexibility for higher-capacity drive packages while retaining the rugged, modular advantages of the Motovario B Series bevel helical gearbox range.

FAQ
What type of application suits a 58.97:1 ratio best?
A 58.97:1 ratio is typically selected for applications that need a balanced mix of output speed reduction and torque multiplication. It works well where you want to moderate output speed while gaining a more noticeable increase in transmitted torque.
Is this gearbox suitable for continuous industrial use?
Yes — this B163 configuration is intended for industrial duty and is well suited to continuous-running applications when correctly matched to the motor, load, and service factor. For best results, always confirm torque demand, duty cycle, and mounting arrangement before installation.
Configuration Notes
Input flange note: the 180B5 IEC input is designed for larger motor frame compatibility, making this version a strong choice for heavier-duty drive systems that require a secure flange-mounted motor connection.
Output bore note: the 100mm hollow bore is intended for larger driven shafts, helping provide dependable shaft retention and stable torque transmission in more demanding mechanical setups.
Application example: ideal for conveyors, mixers, packaging lines, process machinery, and material handling systems where a larger shaft output, robust right-angle drive layout, and stronger torque multiplication with lower running speed are needed for efficient industrial operation.
