Cutting-edge, customised technology for even the most specialised application areas

Special gears

Special solutions, tailored to your requirements

The term ‘special gear’ refers to any gears that do not correspond to a standard, and that can therefore not be selected from the standard catalogue. As a rule, the necessary requirements in terms of dimensions, torques, speeds, service life, installation positions, design and number of input and output shafts, for example, cannot be met by standard gears, since the use of such gears inevitably means a compromise. Only a “lid manufacturer” can provide you with the right “lid” for your “pot”. Special gears have been specially developed, designed, produced and assembled according to customer requirements.

Advantages

The special gearboxes, which correspond exactly to the requirements of the customer, are characterized by their robustness, longevity and efficiency. If we do not have gearboxes that the customer needs, these are developed in cooperation with the customer.
