Aluminium pulleys
With over 100 years of experience in the design and manufacture of belt drives, we are a powerful partner for your drive solution. We manufacture aluminum drive pulleys for machines where the ratio between low dead weight and high strength plays an important role.
The production of individual geometries according to specifications or drawings - including drilling patterns for flanges, couplings, brake discs or counterweights - is a matter of course for us.
From a lot size of 1 piece - for urgent spare parts, prototypes, pilot series models or small series - drive pulleys made of aluminum are produced for you according to customer specifications or drawings with the highest precision.
The best solutions for individual drives are developed in close
cooperation with the customer. The execution in many common aluminum alloys,
also with special properties, is possible.
