In the process of initial development and subsequent performance enhancement of high-reliability bearings for railway rolling stock, it is crucial to fully grasp the actual operating conditions and replicate them to the maximum extent in evaluation experiments. Ensuring the stability and ride comfort of rail vehicles is a vital mission of railway bearings. Depending on the railway gauge, wheel diameter, and axle load, wheel sets can have different configurations and designs. Since all these systems are critical to the performance and reliability of railway vehicles, careful consideration should be given when selecting bearing solutions. Drive systems used in railway trains, such as gearboxes or traction motors, must possess characteristics of high power, sustainability, cost-effectiveness, and low maintenance requirements. These requirements are becoming increasingly important as maintenance intervals become longer and the weight of railway vehicles increases.

Electric motors must provide high rotational speeds and withstand shock loads, while also having to resist low-load conditions, such as during coasting or cruise control modes. Furthermore, sensitivity to electrical discharge creates unique design challenges for motor bearings. These all place high demands on bearing configurations. Specific challenges include a wider operating temperature range, high shock loads, and an increase in the overall load combined with the drive to reduce friction within the gearbox and lower energy consumption. We offer a variety of solutions designed to help ensure reliable and cost-effective operation, improving fleet operational efficiency and reliability. Our railway-specific products and services allow you to fully utilize the performance potential of bearings, thereby helping you reduce life cycle costs. In wet and contaminated environments, we achieve sustainable and cost-effective operation with minimal maintenance, realizing robust, sustainable, and cost-effective railway operations.
