WSO V-belt pulley

WSO V-belt pulley - Weight - Stress - Optimised
Specially developed and optimised high-performance V-belt pulley for heavy duty drives. Our design capabilities and calculations result in optimum solutions.

In combination with the design and high-quality cast material EN-GJS-500-7 (GGG-50), a weight reduction of up to 50% compared to comparable pulleys in the performance class is possible.

The patented design of the FEM-bionically optimised arm structure favours an optimal stress distribution of the acting forces within the V-belt pulley. Furthermore, this special design offers application possibilities independent of the direction of rotation.

With our design and calculation options, we offer individual application-optimised solutions according to customer specifications.


  • Long service life due to wear-resistant material

  • Perfect for high speeds or rotational speeds

  • Ideally suited for mobile systems

  • For all common profiles of drive pulleys

  • Extremely low noise at high speeds

  • Easy installation due to low weight

  • Areas of application

Areas of application

The WSO V-belt pulley is ideally suited for drives subject to high impact loads such as crushers, chippers and shredders, as well as applications with high speeds such as compressors and fans. Due to its low weight, it is also perfect for highly loaded mobile drives in agriculture and forestry.
