NYZ Railway Bearings

Railway bearings are used in railways. Railway freight cars do not have axle boxes. The bearings are connected to the bogie side frames through load-bearing saddles. The bearings bear the impact load generated between the wheelset and the bogie frame.

To withstand the axial load generated when the vehicle turns. The wheel bearing structure includes cylindrical roller bearings, cylindrical roller bearing units, tapered roller bearings, and tapered roller bearing units. According to the application requirements of railway bearings, wheel shaft bearings should have long Maintenance-free cycle, maintenance-friendly structural design and high reliability.
