Overview
B063 9.16:1 bevel helical gearbox with a 30mm hollow bore output and 71B5 IEC motor input for compact 90° right-angle drive integration.
Optimised for industrial reliability, it offers stable speed reduction, high torque density, and dependable performance for OEM builds and retrofits.
Low reduction: This low reduction ratio maintains higher output speeds while still multiplying torque, ideal for fast-moving conveyors, indexing, and light-to-medium duty automation.
This configuration features a 30mm hollow output bore and 71B5 IEC motor input (Ø160 × 14 flange), providing reliable speed reduction and robust torque delivery for conveyors, automation systems, packaging machinery, and OEM equipment builds. The 71B5 flange configuration supports larger IEC frame motors, offering increased input torque capacity and broader motor compatibility compared to smaller frame options.
Part of the modular Motovario B063 bevel helical gearbox range, this unit offers flexible mounting, IEC motor compatibility, and proven long-term durability.
