The economical solution for classic flat belt drives, transport systems and bucket elevators. Benefits result from a large assortment with an extensive stock store and fast availability. Flat belt pulleys in all common diameters are available from stock.

Ready drilled flat pulleys are usually balanced in grade G16, upon request G6.3 or G2.5 are also possible.

Individual drives require individual solutions. In the event of deviations from DIN 111, the need for special geometries, intermediate sizes or higher peripheral speeds, it is possible to produce exclusive custom-made products.

All geometries can be easily produced by a flexible, model-free moulding process. From lot size 1 piece , for requirements as urgent spare parts, prototypes, pilot series models or small series , flat belt pulleys are produced according to customer specifications or drawings.

The design in alternative materials (EN-GJS, steel, aluminum, plastic, etc.) is also possible.
