Tec FCNDK110 40:1 Worm Gearbox – 42mm Bore, 100-112B14 Input

This Tec FCNDK110 40:1 worm gearbox combines a 42mm hollow bore output with a 100-112B14 IEC input flange in a proven modular housing. It is a strong choice for larger process drives, screw conveyors, mixing systems, and torque-demanding machinery where buyers need slower output speed with stronger torque multiplication in a compact right-angle package.
