Special design V-belt pulleys

Customised manufacturing for direct assembly

As a specialised iron foundry focusing on industrial drive technology, we are your expert partner for ready-to-install V-belt pulleys in special designs. We manufacture customised V-belt pulleys in accordance with DIN 2211 / DIN 2217 – in all common profiles such as SPZ, SPA, SPB or SPC – with diameters up to 2,500 mm and unit weights up to 6,000 kg.

Thanks to our flexible moulding process, we can respond to your requirements quickly, economically and without model costs. In our own foundry, we manufacture all pulleys to fit perfectly – from one-off production to small series.

As a complete manufacturer, we take care of the entire production chain – from design and casting to mechanical processing on state-of-the-art CNC machines.

On our Schenk balancing machines, we ensure that your components are perfectly balanced – on request, also on a contract basis. We also offer various surface treatments, refinements and galvanising to optimally prepare your components for use in industrial environments.

V-belt pulleys for industrial applications

Further variants

V-ribbed pulleys / Poly-V pulleys

In addition to classic V-belt pulleys, we also manufacture ribbed pulleys/Poly-V pulleys (profiles H, J, K, L, M) in special designs according to individual customer specifications. They are ideal solutions for multi-track or particularly compact drive systems.

V-belt pulleys as steel/welded construction

Since drive elements made of grey cast iron, spheroidal graphite cast iron or cast steel cannot be used in some applications, we also produce drive and flywheels as steel/welded constructions. This design offers increased stability despite its lower mass and is used primarily for large drive wheels with high workloads.
