The right choice of material is very important for shaft-hub connections. Stainless steel in particular offers a variety of possible applications in the field of stainless steel constructions. Shaft-hub connections made of stainless steel are increasingly being used in industry today. One reason for this is that the demands placed on components in certain industries are becoming ever more stringent, while at the same time the machining of stainless steels has become easier. Stainless products in drive technology are characterised in particular by their resistance to chemically aggressive substances and are therefore increasingly being used in the food and packaging industries, maritime technology, laundry technology and laboratory equipment. In general, stainless products are used wherever increased risk of corrosion and purity are important criteria.

The standard stainless steel we use is 1.4122, which is a stainless, martensitic steel with good resistance to corrosion and very good wear resistance. If the product is to be used in a more aggressive environment, 1.4571 is the preferred material. This austenitic stainless steel offers very good corrosion resistance and is also suitable for low temperatures and elevated temperatures up to 550°C.

However, it should be noted that despite good mechanical properties, products made from stainless steel achieve lower transfer values than comparable products made from standard materials such as 42CrMo4+QT. In addition to the mechanical properties of the steels, the mechanical properties of the tensioning screws are decisive for this. The strength values of stainless clamping screws are significantly lower than the strength values of high-strength steel screws. As a rule, however, the transmission values of stainless products are sufficient for their use. If this is not the case, customised solutions can be implemented quickly and easily.
