Tec FCNDK110 100:1 Worm Gearbox – 42mm Bore, 90B14 Input

Built around the FCNDK110 modular worm gearbox platform, this 100:1 version gives buyers a compact right-angle drive with 42mm hollow bore output and 90B14 motor input compatibility. It is commonly selected for slow-speed heavy-duty applications, high-reduction transfer systems, and machinery where strong torque output is critical where very slow output speed for high-reduction, higher-torque applications 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 90B14 motor input and 42mm output bore are already specified, while the 100:1 ratio delivers approximately 14rpm output speed from a 4 pole 1400rpm motor.

---

Why Choose This Configuration?

This very high-ratio configuration is intended for applications needing very slow output speed and substantial reduction. It is a sensible choice for controlled positioning, heavier-duty slow-running drives, and equipment where higher torque at lower speed is more important than fast output.

Frequently Asked Questions

What output speed does a 100:1 FCNDK gearbox give?

In the TEC catalogue performance table, this FCNDK110 100:1 configuration is shown with a nominal output speed of about 14rpm when used with a 4 pole 1400rpm motor at service factor 1.

What is this gearbox commonly used for?

This gearbox is commonly used for slow-speed heavy-duty applications, high-reduction transfer systems, and machinery where strong torque output is critical, and other machinery needing very slow output speed for high-reduction, higher-torque applications in a compact right-angle drive.

Is the housing aluminium or cast iron?

For FCNDK110, the catalogue lists the housing as cast iron housing.

Does this gearbox come with lubricant?

According to the TEC FCNDK catalogue summary, this size is supplied with synthetic long-life oil grade ISO VG 320 and fitted with a breather plug.

Can I fit different IEC motor inputs to the FCNDK range?
