Linear shafts

Steel shafts/linear shafts are very commonly used machine elements and are the primary component of linear guidance. MISUMI manufactures and supplies more than 550 types of steel shafts/linear shafts with over a billion configuration possibilities for a whole range of industrial applications, such as packaging, powertrain and body-in-white. When combined with our large range of linear ball bearings you can put together a machine optimally configured for guidance functions of every type.

Steel shafts/linear shafts are available in lengths between 10 and 1,500 millimetres, with a radius of between 3 and 50 millimetres. There are different precision categories - standard and precision, as well as tolerance categories of g6 and h5. They are made from surface-hardened steels: 1.3505/100Cr6 and 1.4125/X105CrMo17. The machine with the tolerance level of f8 is made from 1.1191/C45E and 1.4301/X5CrNi18-10 steel, which is surface-hardened (hard chrome plating) You can see this type of shaft in a centering unit.

The steel/linear shafts can be optimised according to the intended purpose using surface treatment if there are specific operational requirements. MISUMI offers steel/linear shafts with surfaces treated with hard chrome plating or low temperature black chrome plating (LTBC coating). Depending on the process, users’ products will benefit from improved properties in terms of hardness, wear and corrosion resistance, friction, adhesion, appearance or reflection. The lifespan of LTBC coated components is significantly increased thanks to better corrosion prevention and reduced abrasion.

With multiple options regarding dimensions and shape - even for different ends and a threaded version - you can precisely configure the steel/linear shafts according to the requirement. Using MISUMI is faster and cheaper compared to conventional manufacturing that is in-house or contracted out. The need for component drawings and production planning is eliminated completely. Cost savings of 70 percent and time savings of 68 percent can be achieved by choosing MISUMI over a general manufacturing company or another provider for obtaining a thermally treated, surface-coated and customised steel/linear shaft.

As with all MISUMI products, our steal/linear shafts are manufactured to the highest quality assurance standards. MISUMI processes orders within Germany for as small as 1 product without shipping costs, small quantity surcharge, or a minimum product or order value.

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.
