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 use conditions and restore them to a greater extent in the evaluation experiment. 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 group can have different configuration and design. Since all of these systems are critical to the performance and reliability of railway vehicles, careful consideration should be given to the selection of bearing solutions. The drive systems used for railway trains, such as gearboxes or traction motors, must have the characteristics of strong power, sustainability, cost-effectiveness and low maintenance requirements. As the maintenance interval is getting longer and longer and the weight of railway vehicles is also increasing, these requirements are becoming more and more important.

The motor must provide high speed and withstand impact loads, and must also resist low load conditions, such as taxiing or cruise control modes. in addition, the sensitivity to discharge makes motor bearings face unique design challenges. These pose high requirements for bearing configuration, including a larger operating temperature range, high impact loads, and an increase in the overall load combined with the drive to reduce friction and energy consumption in the gearbox. we offer a variety of solutions designed to help ensure reliable and cost-effective operations and improve fleet efficiency and reliability.

Our railway-specific products and services allow you to take full advantage of the performance potential of bearings, thereby helping you reduce life cycle costs and achieve sustainable and cost-effective operation with less maintenance in humid and polluted environments. achieve robust, sustainable and cost-effective railway operations.
