Gear manufacturer, gearbox manufacturer and hardening plant

We are manufacturers of gears and gearboxes with maximum service life and precision

TANDLER Gearboxes

There is no getting around the potential of the gearbox wherever rotational movements have to be transmitted precisely and permanently. The fact that our gearbox series can be combined and your wishes taken into account means maximum flexibility

We will support you during the development of your special gear unit right from the design drawing. The gears we manufacture will be specified individually according to your requirements. This can involve a custom-made design or a variation of our standard gearboxes.

Special gearboxes

We have been manufacturing gears and gear parts of the highest quality for 70 years now. We manufacture individually or in series entirely in Germany. We are able to offer a 100% real net output thanks to our in-house hardening plant.


Gears and gearboxes from Germany since 1949

As a family-owned company founded over 70 years ago in Bremen, we now have over 200 production specialists serving the global market.

In addition to our standard products, we are also specialised in the design and manufacture of small batch numbers according to individual customer requirements. In doing so, we can provide a 100% real net output – from design to heat treatment to grinding – everything at one location.
