Tec FCNDK40 100:1 Worm Gearbox – 18mm Bore, 63B14 Input

This Tec FCNDK40 100:1 worm gearbox combines a 18mm hollow bore output with a 63B14 IEC input flange in a proven modular housing. It is a strong choice for positioning systems, slow-turning mechanisms, compact handling equipment, and controlled movement applications 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 63B14 input, 18mm hollow output, and a nominal output speed around 14rpm 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.
