Tec FCNDK63 80:1 Worm Gearbox – 25mm Bore, 80B5 Input

This Tec FCNDK63 80:1 worm gearbox combines a 25mm hollow bore output with a 80B5 IEC input flange in a proven modular housing. It is a strong choice for agitators, dosing systems, slow conveyors, and machinery requiring substantial speed reduction where buyers need very slow output speed for high-reduction, higher-torque applications in a compact right-angle package.

Gearbox Overview

Within the TEC FCNDK series, this version is aimed at machines needing a combination of 80B5 input, 25mm hollow output, and a nominal output speed around 17rpm with a 4 pole motor. The modular format also supports multiple mounting positions including B3, B6, B7, B8, V5, and V6.

Why Choose This Configuration?

This very high-ratio configuration is intended for applications needing very slow output speed and substantial reduction. It is a sensible choice for controlled positioning, heavier-duty slow-running drives, and equipment where higher torque at lower speed is more important than fast output.
