Steering spindles and steering shafts - In one step, from one piece

Steering spindles, steering shafts and other steering elements are produced for the international market by Felss Rotaform, the component manufacturer that is part of the Felss Group located in the USA, China, Germany and Switzerland. Also ThyssenKrupp Presta, one of the most successful global manufacturers of steering systems, uses the know-how of Felss Rotaform for its production of steering spindles.

International rotary swaging and axial forming specialist

A functional, international production network is crucial to the success of Felss Rotaform, stresses Rolf Käser, Managing Director of Felss Rotaform Switzerland: “We produce different components by order of ThyssenKrupp Presta at our sites in Germany, China, Switzerland and in the foreseeable future probably also in the USA. The company has chosen us as their strategic partner because it is aware of our know-how as a provider of ready to install components for tube forming, and that we continue to once more provide the necessary component quality at the different sites.”

Advantages of axial forming

A typical example of this know-how and the resulting, qualitative upmarket components that are produced can be seen at the Felss Rotaform site in Switzerland: Steering shafts are produced here by order of ThyssenKrupp Presta for use in a small car of a German car manufacturer. One particular feature here: The whole component is produced from just one tube using the rotary swaging and axial forming process. For years, the steering spindle was produced from two separate parts, requiring much greater effort.

A complete solution for steering components

In this regard it is also interesting that the tube supplier deploys a completely new blank from the start of production. After welding, it is no longer annealed in the furnace but during a new kind of heating process on the welding system. It is therefore no surprise that this decision too was taken in consultation with Felss Rotaform. Käser says: “As a full service provider, we introduce the know-how from the system development stage to the trouble-free serial production. We take responsibility for all important factors such as for example selecting the correct tube as the base material.” Ultimately, it is the customer, ThyssenKrupp Presta who benefits from an all-in-one solution for its steering components, for which Felss Rotaform is responsible for its quality and efficiency.
