Tec FCNDK110 40:1 Worm Gearbox – 42mm Bore, 90B5 Input

Built around the FCNDK110 modular worm gearbox platform, this 40:1 version gives buyers a compact right-angle drive with 42mm hollow bore output and 90B5 motor input compatibility. It is commonly selected for larger process drives, screw conveyors, mixing systems, and torque-demanding machinery where slower output speed with stronger torque multiplication is needed without overcomplicating the drive layout.

Gearbox Overview

The FCNDK110 size sits in the very heavy part of the range and uses a cast iron housing. In this configuration, the gearbox is suited to installations where a 90B5 motor input and 42mm output bore are already specified, while the 40:1 ratio delivers approximately 35rpm output speed from a 4 pole 1400rpm motor.

Why Choose This Configuration?

This higher-ratio version is normally selected where the application needs stronger torque multiplication and slower shaft speed than lower-ratio options can provide. It works well for feeders, mixers, transfer drives, and machinery with more demanding load conditions.
