Railway bearing application


Railway transportation is a fast-growing industry. Bearings are also indispensable in the railway production and application industry. Bearings used in the railway industry must have high load carrying capacity and safety performance.

Railway bearing application railway, axle bearing railway locomotive vehicle axle system adopts different structural design due to different application conditions. The locomotive and passenger car have axle box, the bearing is connected with the bogie through the axle box, the railway freight car has no axle box, and the bearing passes the bearing saddle and Bogie side frame connection. The bearing is subjected to the impact load generated between the wheel set and the bogie frame, and is also subject to the axial load generated by the vehicle turning. The axle bearing structure comprises a cylindrical roller bearing, a cylindrical roller bearing unit, a tapered roller bearing, and a tapered roller bearing unit.


High-speed rail bearing

The bearing running speed is above 200km/h, which requires the bearing to have high bearing capacity and safety performance;

Since the double row tapered roller bearing has a good sealing structure and the clearance has been adjusted before installation, the high iron bearing often uses this type of bearing.

Locomotive bearing

The railway locomotive bearing vehicle axle system adopts different structures due to different application conditions. The locomotive bus has an axle box, and the bearing is connected to the bogie through the axle box. Cylindrical roller bearings are often used.

Truck bearing

Cylindrical roller bearings are often used for wheelset bearings.

Subway bearing

Generally, it is a double row cylindrical bearing with sealing device on both sides or two matched single-row cylindrical roller bearings with one-side sealing device. The bearing is pre-installed with grease.
