The economical combination of various processes.
Hollow shafts transmit rotary movements and torques between parts that are firmly connected to them. Hollow shafts are used when weight has to be saved or the shaft has to have a high inherent frequency.
Reduced material usage and lightweight construction for resource-efficient results
This Felss hollow shaft was produced with a 90° shoulder using the forming process, whereby a large progressive ratio had to be produced with maximum precision. The challenge was overcome by economically combining cold forming, turning, hardening and grinding. The processes used ensure increased component strength. A collaborative development phase has led to this hollow shaft combining advanced functional integration with maximum resource efficiency.
