Toothed or timing belt pulleys

With over 100 years of experience in the design and manufacture of belt drives, we are a powerful partner for your drive solution.

Toothed or timing belt pulleys are an important drive element for slip-free synchronous drives. We can manufacture pulleys for all common profiles as well as special profiles from the leading manufacturers. The scope of delivery includes both standard bearing plates as well as special custom-made products up to a diameter of >2,000 mm.

All geometries can be easily manufactured using a flexible, model-less moulding process. From a batch size of 1 piece, for urgent spare parts, prototypes, pilot series models or small series, toothed belt pulleys can be produced according to customer specifications or drawings. The design is also possible in alternative materials (EN-GJS, steel, aluminum, plastic, etc.). The ideal solution for individual drives is developed in close cooperation with the customer.

 

With the toothed or timing belt and the matching toothed belt pulleys, perfectly matched belt drives are available
