Bearings for Railroad Vehicles
Three kinds of bearings .Bearings for axles, gear boxes and traction motors. Exclusive design for each application.
Cylindrical roller bearings are mainly used for axles with heavy radial load (Double-row tapered roller bearings have also used recently).
Tapered roller bearings are used for gear boxes where large thrust loads are expected.
Deep-groove ball bearings and cylindrical roller bearings are used for traction motors.
Feature Design: Double-row tapered roller bearing JT21 support radial and axial loads on raceway. Excellent running stability due to the minimum axial clearance; Outstanding high-speed-operation performance; Maximum speed: 285km/h
Application:
For axles Double-row cylindrical roller bearings or Double-row tapered roller bearings are used according to the vehicle characteristic.
Cylindrical roller bearings are widely used because of their capability for high speed rotation and ease of maintenance.
Recently, tapered roller bearings are also used because they are suitable for high speed operation and they can be used for a long period of time without disassembly.
