In the process of early development and later performance improvement of high reliability bearings for rail transit, it is very important to fully grasp the actual usage conditions and restore them to the maximum extent in evaluation experiments. Ensuring the stability and ride comfort of rail vehicles is an important mission of railway bearings. According to the railway gauge, wheel diameter, and axle load, the wheel set can have different configurations and designs. As all these systems are crucial for the performance and reliability of railway vehicles, careful consideration should be given when selecting bearing solutions.

The motor must provide high speed and withstand impact loads, and must also resist low load conditions, such as in coasting or cruise control mode. In addition, the sensitivity to discharge also presents unique design challenges for the motor bearings. These all place high demands on bearing configuration, with specific challenges including a larger operating temperature range, high impact loads, and an increase in overall load combined with the drive to reduce friction in the gearbox and lower energy consumption. We offer a variety of solutions aimed at ensuring reliable and cost-effective operations, improving fleet efficiency and reliability.
