Rail Transit

In the process of early development and later performance improvement of high reliability bearings for railway trains, 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 riding comfort of railway 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 drive system used for railway trains, such as gearboxes or traction motors, must have the characteristics of strong power, sustainability, high cost-effectiveness, and low maintenance requirements. Due to the increasing maintenance intervals and weight of railway vehicles, these requirements are becoming increasingly important.

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.

Our railway specific products and services allow you to fully utilize the performance potential of bearings, thereby helping you reduce lifecycle costs, achieve sustainable and cost-effective operation with minimal maintenance in humid and polluted environments, and achieve robust, sustainable, and cost-effective railway operations.
