We manufacture gears for the following

Raw material and mining industry

Constant system availability in the harshest operating conditions: our gearboxes for the raw material and mining industry are designed and manufactured for these special operational conditions in close cooperation with our customers. Our ...

Cement industry

The gearboxes we develop and manufacture are specifically designed for the harsh conditions in cement works. Our cement industry gearboxes are durable and easy to maintain, while also being relatively lightweight.

We already have suitable ...

Rolling mill technology and metallurgy

We have the right solutions for this harsh industrial segment too. Coiler and Reel gearboxes, pinion gearboxes, diver gearboxes, straightening machine gearboxes, mill and dryer gearboxes, scissor gearboxes, roller conveyor gearboxes and ...

Marine and offshore technology, shipbuilding, shipyard industry

Our tradition of manufacturing propeller gearboxes and generator gearboxes (marine gearboxes) spans more than 50 years. Each and every project aims to deliver maximum quality and precision taking into account all of the customer’s specific ...

Materials handling technology

A wide range of gearbox types with different properties are used in materials handling technology. What all of the gearboxes have in common is that they must be robust and reliable! Whether drive or hoisting gearbox in mobile systems or ...

Kneading and mixing technology

Our mixing and kneading gearboxes are particularly powerful and robust when it comes to both providing the necessary torque for mixing and kneading and withstanding the prolonged backpressure, especially with highly viscous media.

Of ...

Energy, oil and petrochemical industry

Low-vibration at maximum speed: our turbo spur wheel and turbo planetary gearboxes for fast running work machines (turbines, compressors, generators, etc.) are subject to the most stringent quality standards during their design and ...

Wind and water power technology

We do our bit for the environment too!

We make new gearboxes and repair old gearboxes by various manufacturers for the renewable energy industry. ...

Gears for mobile equipment

Our rotation and slewing gearboxes are made up of modules from a tried and tested assembly system. The planetary kits are also used in integrated winch and industrial gearboxes and are therefore very economical to manufacture. ...

General machine construction

Of course, we also produce a wide range of gearbox types (such as test bench gearboxes) for general machine and plant construction. If you haven’t yet found the right drive solution in the industrial segments listed, we will be happy to ...

We were allowed to process a 2-piece welded mill girth gear, module 25, for a well-known plant manufacturer from Austria.

Our task was the complete machinig of the welded semi-finished product provided by the customer.

In order to minimize component distortions during processing as far as possible, all work steps (turning, milling and gear cutting) were carried out once as preliminary and then again as finishing steps.

GearTec AG is currently able to process girth gears with a diameter of up to 4000 mm.

We have once again been able to produce several furnace/mill pinions for a large German plant manufacturer.

This time, at the request of our customer, the pinions were delivered without shafts because they are spare parts.

The pinions in module 28 and module 30, made of 30CrNiMo8+QT, were finish ground to gear quality 5 after gear milling.

For several customers we've designed and manufactured different crane gearboxes (as 1:1 replacements) for old gearboxes.

Here are a few examples of our hoisting and traveling gearboxes with nominal power from 20 kW up to 132 kW:

Hoisting gearbox MS013C44:
Power 132 kW; Input speed 1000 rpm; Ratio 1:44

Traveling gearbox MS003C19:
Power 29 kW; Input speed 1000 rpm; Ratio 1:19

Traveling gearbox MS003D16:
Power 30 kW; Input speed 750 rpm; Ratio 1:16

Traveling gearbox MS002C30:
Power 20 kW; Input speed 1000 rpm; Ratio 1:30
