TBU 90 Taper roller bearing Railway bearing

Railway bearing is a kind of application in railway bearing, wheel bearing railway locomotive vehicle shaft systems with different application conditions with different structural design, locomotives, passenger car axle box, bearing through the axle box connected to the bogie, railway wagon axle box, bearing with bogie side frame connected by load-bearing saddle bearing wheel and impact load between the bogie frame, and more Corners is under the axial load of wheel bearing structure contains a cylindrical roller bearing, cylindrical roller bearing unit, taper roller bearing, tapered roller bearing units according to the application requirements of railway bearing, wheel bearing should have long maintenance cycle, convenient maintenance and high reliability of structure design.

Bearings for high speed railways.The bearings run at speeds above 200km/h and require high load carrying capacity. As the double row tapered roller bearings have a better sealing structure and the clearance has been adjusted before installation, this type of bearing is mostly used for high speed railways.

Bearings for locomotivesRailway locomotive bearing vehicle axle system due to different application conditions using different structures, locomotive passenger cars have axle box, bearing through the axle box and bogie connected. Generally use more cylindrical roller bearings.

Bearings for freight carsWheel pair bearings generally use more cylindrical roller bearings.

Underground bearingsGenerally for both sides with sealing device double row cylindrical bearings or two pairs of single side with sealing device single row cylindrical roller bearings, bearing pre-installed grease.
