Tec FCNDK90 25:1 Worm Gearbox – 35mm Bore, 100-112B14 Input

This Tec FCNDK90 25:1 worm gearbox combines a 35mm hollow bore output with a 100-112B14 IEC input flange in a proven modular housing. It is a strong choice for mixers, conveyors, general process machinery, and industrial handling applications where buyers need balanced reduction with practical output speed and useful torque increase in a compact right-angle package.


Gearbox Overview

Within the TEC FCNDK series, this version is aimed at machines needing a combination of 100-112B14 input, 35mm hollow output, and a nominal output speed around 56rpm 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?
