V-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. We manufacture individual V-belt pulleys in all common profiles up to a diameter of 2,500 mm.

With our moulding process, we can mould all drive pulleys flexibly, quickly and without model costs and manufacture them in our own foundry. Whether it be V-belt pulleys, flat belt pulleys, flywheels or special drives such as lattice drums - we process them on the most modern CNC machines as a complete service from a single source.

Unit weights of up to 6,000 kg are possible without any problems. Our drives are then perfectly balanced on our Schenck balancing machines. We can also carry out sub contract balancing for our customers. We also offer surface treatments such as finishing or rubber coating.
