Flat belt pulleys

With over 100 years of experience in the design and manufacture of belt drives, we are a powerful partner for your drive solutions. We manufacture individual flat belt pulleys in all common profiles up to a diameter of 2,500 mm.

Flat belt pulleys are important and versatile drive element in many areas. Flat belt drives have clear advantages, especially in cases where the drives that are subject to shock loads, and which are also subject to vibration. The discs are very economical and highly reliable.

In order to meet the performance requirements of our customers, all of our drives are individually designed. Weight, moment of inertia, geometry and performance parameters are perfectly matched to the requirements. Due to our flexible semi-automatic molding process, there are no model costs for the initial production. Similarly, there are no costs for any geometry adjustments before the moulding process. This flexible process enables the most economical production and guarantees minimum delivery times with maximum responsiveness.
