Application-specific special features
Axlebox bearings for locomotives are characterized by their particularly high load ratings. For safety reasons, the bearings used in high-speed transportation applications are manufactured from steel that is subject to specific requirements with regard to the purity of the material. These bearings are equipped with non-contact seals to allow them to be operated at low temperatures, and special high-speed grease is also used.

Trains used in local passenger transport have to brake every few minutes, which poses a particular challenge for the lubricating grease. Contrastingly, the bearings used in long-distance passenger transport are designed for higher speeds. The low-floor design of some streetcars means that bogies cannot be used, so low-floor axles with individual bearing supports are used instead.
