Railway bearings play a crucial role in locomotives and rolling stock, specifically in the wheel axle systems. They are designed differently depending on the specific application conditions. Locomotives and passenger cars utilize axle boxes to connect the bearings to the bogie frame, while railway freight cars connect the bearings to the bogie frame through bearing saddles.

 

These bearings endure the impact loads between the wheel sets and the bogie frame, as well as axial loads during vehicle turning. They can be cylindrical roller bearings, cylindrical roller bearing units, tapered roller bearings, or tapered roller bearing units. To meet the demands of railway applications, wheel axle bearings should have a long maintenance-free lifespan, a user-friendly design for maintenance, and exceptional reliability.
