Q: What kind of bearings can be used in train wheels?
A: Railway roller bearing applies in railway. Axle bearing Railway wheel vehicle axle system adopts different structural designs due to different application conditions. The locomotive and passenger train have axle boxes, and the bearings are connected to the bogie through the axle boxes. There is no axle box for the train wagon, and the bearings connect with the side frames of the bogies through bearing saddle. The bearing bears the impact load between the wheelset and the bogie frame and also bears the axial load generated by the turning of the vehicle. The wheel shaft bearing structure includes cylindrical roller bearing, cylindrical roller bearing unit, tapered roller bearing and tapered roller bearing unit.
