Tec FCNDK40 30:1 Worm Gearbox – 18mm Bore, 56B5 Input

Built around the FCNDK40 modular worm gearbox platform, this 30:1 version gives buyers a compact right-angle drive with 18mm hollow bore output and 56B5 motor input compatibility. It is commonly selected for compact conveyors, transfer systems, metering equipment, and general automation where balanced reduction with practical output speed and useful torque increase is needed without overcomplicating the drive layout.

Gearbox Overview

The FCNDK40 size sits in the compact part of the range and uses a pressure die-cast aluminium housing. In this configuration, the gearbox is suited to installations where a 56B5 motor input and 18mm output bore are already specified, while the 30:1 ratio delivers approximately 46rpm 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.
