This hollow shaft is used for motors . Material is C45 steel. Tempering and Quenching heat treatment.

The primary advantage of the hollow shaft’s characteristic construction is the enormous weight saving that it brings about, which is advantageous not just from an engineering but also from a functional point of view. The actual hollow itself has another advantage – it saves space, as operating resources, media, or even mechanical elements such as axles and shafts can either be accommodated in it or they make use of the workspace as a channel.

The process of producing a hollow shaft is far more complex than that of a conventional solid shaft. In addition to the wall thickness, material, occurring load and acting torque, dimensions such as diameter and length have a major influence on the hollow shaft’s stability.

The hollow shaft constitutes an essential component of the hollow shaft motor, which is used in electrically powered vehicles, such as trains. Hollow shafts are also suitable for the construction of jigs and fixtures as well as automatic machines.
