Development and Manufacturing of Special Gearboxes
Your requirements are our design brief.

Standard gearboxes are a good choice for many applications. But there are cases where the installation space, gear ratio, drive concept, or environmental conditions are so specific that no off-the-shelf product offers a solution that is both economically and technically sound.

This is exactly where CHEMNITZER ZAHNRADFABRIK excels.

We develop and manufacture custom gearboxes for drive torques up to 10,000 Nm—electrically, hydraulically, or pneumatically driven, in all common gearbox types and their combinations. Whether it’s tight installation spaces, high safety requirements, extreme environmental conditions, or the integration of clutches, brakes, and sensors—we’ll find a solution that’s technically sound and works reliably.

Our promise: No compromise between what you need and what we deliver.

 

What makes a CZF special gearbox special?

Our special gearboxes are not created by adapting a modular system, but through genuine engineering work: from the design of the gearing to the selection of bearings and the choice of suitable materials and surface finishes.

What this means in practice:

  • Unlimited gear types
    Spur, bevel, worm, and planetary gears, as well as any combination, depending on the requirements profile

  • Flexibly combinable drive concepts
    Electric, hydraulic, pneumatic, or as a hybrid solution

  • Integration of additional components
    Clutches, brakes, transducers, and sensors are seamlessly integrated

  • High level of vertical integration at the Chemnitz site
    Design, manufacturing, and assembly all under one roof

  • Close communication with customers
    From the initial consultation through to commissioning

 

In which industries and applications does CHEMNITZER ZAHNRADFABRIK have expertise?

Virtually all of them. CZF special gearboxes are used wherever standard solutions reach their limits:

  • Extrusion & Plastics Technology
    High torques, tight installation spaces, continuous operation

  • Defense & Security Technology
    Maximum reliability, robustness, and quality certification

  • Marine & Offshore

What is a special gearbox?

A special gearbox is a custom-designed drive component engineered specifically for a defined application. Unlike standard gearboxes, there is no such thing as an off-the-shelf special gearbox: Each unit is built based on your specific requirements—in terms of gear ratio, installation space, drive type, environmental conditions, and service life.

How does a special gearbox project work?

It all starts with a conversation. Our design engineers take the time to fully understand your requirements—speed, torque, mounting dimensions, and environmental conditions. Based on this, we develop a concept, design the gearbox, engineer it, and manufacture it at our plant in Chemnitz. We remain in close contact with you throughout the entire process.

What types of gearboxes does CHEMNITZER ZAHNRADFABRIK specialize in?

We specialize in all major types: spur, bevel, worm, and planetary gearboxes, as well as multi-stage combinations. The right design is determined by your requirements—not by a catalog.

Are there any limitations?

Hardly any, within the laws of physics. Our current state-of-the-art manufacturing technology enables solutions in the drive torque range up to 10,000 Nm. For very specific requirements, we’ll openly discuss what makes sense from both a technical and economic standpoint.
