RAILWAY BEARING TAPERED ROLLER BEARING HM120848/HM120817XD TAROL4X8-U-JP

HM120848/HM120817XD Railway bearings are applied to railways. The wheel and axle bearings of railway locomotives and vehicles adopt different structural designs due to different application conditions. Locomotives and passenger cars have axle boxes, and the bearings are connected to the bogie through the axle boxes. Railway freight cars have no axle boxes.

The railway freight car has no axle box, and the bearing is connected with the side frame of the bogie through the bearing saddle.

Railway bearings withstand shock loads that occur between the wheelset and bogie frame, and also withstand axial loads that occur when the vehicle turns.
