Rail transport

Railway bearings play a crucial role in locomotives and rolling stock, especially in axle systems. They are designed differently depending on the specific application. In locomotives and passenger cars, axle boxes are used to connect the bearings to the bogie frame, while in freight rail cars, the bearings are connected to the bogie frame via bearing saddles.

These bearings support impact loads between the wheelsets and the bogie frame, as well as axial loads when the vehicle is turning. They can be cylindrical roller bearings, cylindrical roller bearing units, tapered roller bearings or tapered roller bearing units. To meet the requirements of rail transport, wheel axle bearings must have a long service life without maintenance, a user-friendly design for maintenance and exceptional reliability.
