Fly wheels and band wheels

We produce band wheels and fly wheels for machines that require high torques and large power development. Oscillating weights and torques are perfectly adapted to their respective drive situation.

Production of individual geometries according to specifications or drawings – including hole patterns for flanges, couplings, brake discs or counterweights – is routine course for us. All geometries can be easily produced thanks to a flexible, model-free moulding process.

Band wheels are produced with the highest precision from batch sizes 1 for urgently needed spare parts, prototypes, zero-series models or series according to individual requests or drawings.

In close cooperation with the customer we develop optimal solutions for individual drives. Implementation is also possible with alternative materials (EN-GJS, steel, aluminum, plastic etc.).
