Welcome to Kumera Getriebe GmbH website.
Former C.u.W. Keller GmbH Co. & KG is now Kumera Getriebe GmbH, subsidiary of Kumera Power Transmissions Group since September 2019


KELLER makes the difference and offers transmission solutions from a single source. We design, produce, repair, maintain and optimize with a passion and experience we have acquired, in particular, in the individual manufacture of custom-made special gearboxes. In everything we do, our special KELLER claim applies: We always work quickly and with absolute precision. For this is how we can guarantee our customers an optimum price-performance ratio.

Our portfolio includes the design and manufacture of gear wheels with diameters of up to 4.0 m and, based on these, the development and production of innovative special transmission units weighing up to 200 tonnes.

For all sectors, we produce unique gearing components and gearboxes to individual specifications. We also maintain, repair or optimize both our own gear units and those of other manufacturers.
