Tec FCNDK75 15:1 Worm Gearbox – 28mm Bore, 80B5 Input

Built around the FCNDK75 modular worm gearbox platform, this 15:1 version gives buyers a compact right-angle drive with 28mm hollow bore output and 80B5 motor input compatibility. It is commonly selected for mixers, conveyors, general process machinery, and industrial handling applications where balanced reduction with practical output speed and useful torque increase is needed without overcomplicating the drive layout.

Gearbox Overview

The FCNDK75 size sits in the heavy part of the range and uses a pressure die-cast aluminium housing. In this configuration, the gearbox is suited to installations where a 80B5 motor input and 28mm output bore are already specified, while the 15:1 ratio delivers approximately 93rpm output speed from a 4 pole 1400rpm motor.

---

Why Choose This Configuration?

This mid-range ratio is commonly chosen when buyers need a balanced reduction that slows the output without making the machine excessively slow. It is a strong all-round option for general machinery, conveyors, packaging equipment, and process systems.
