Motovario B163 14.08:1 Bevel Gearbox – 100mm Bore, 180B5

Overview

Motovario B163 14.08:1 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.

Low Reduction: An 14.08:1 ratio is ideal where a relatively higher output speed is still required, while adding practical torque multiplication for conveyors, transfer drives, packaging systems, and general process equipment.

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 an 14.08:1 ratio best?
An 14.08:1 ratio is typically selected for applications that need moderate speed reduction without slowing the output excessively. It works well where you want to maintain efficient running speed while gaining a useful 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 larger conveyors, bulk handling systems, packaging lines, and processing machinery where a right-angle gearbox, larger shaft bore, and relatively higher output speed are needed in one compact industrial solution.
