Hollow shafts

The structure and function of a hollow shaft in most instances, is similar to a normal shaft. It is used where machine parts perform rotational movements. Thus, a hollow shaft can take over the simple bearing of a rotating machine part and transfer the torque and rotational movement. In doing so, shafts fulfil a very important task, which is why they are used in almost all machines and in all application areas of machine construction.

What is the difference between a hollow shaft and a normal shaft? As the name suggest, the hollow shaft is hollow on the inside. This characteristic gives the hollow shaft different advantages compared to a normal shaft. Not only does is save a lot of weight. The hollow shaft is also used for other components such as axes and shafts or even as a passage for different media.

The production of a hollow shaft is slightly more complicated than that of a normal shaft. In order to avoid instability, the dimensions of the hollow shaft, wall thickness and the material used must be exactly coordinated to one another. Even the subsequent torque, as well as rotational direction must be observed during the configuration of the hollow shaft.

The MISUMI WEBINDEX has different types of hollow shafts.

Furthermore, MISUMI offers hollow shaft configurations, in which a selection can be made from six different shaft ends. Each shaft end can be specified separately for each side of the hollow shaft.

The length and thickness of the shaft as well as the shaft end can be configured differently depending on the hollow shaft. All MISUMI hollow shafts are made of steel (EN 1.3505 equiv.) and can be hard chrome plated. Furthermore, there is a possibility of a LTBC-coating, which is characterised by its particularly high degree of corrosion protection and its stability. More detailed information on the technical details (hardness, wall thickness, and much more) can be derived from the MISUMI WEBINDEX. The respective CAD data of each hollow shaft can be accessed on the respective product pages.
