Rail Transport

In the early development and subsequent performance enhancement of high-reliability bearings for railway trains, it is vital to fully understand the actual operating conditions and replicate them as closely as possible in evaluation tests. Ensuring the stability and ride comfort of rolling stock is a key mission for railway bearings. Depending on the railway gauge, wheel diameter and axle load, wheel sets can have different configurations and designs. As all these systems are crucial to the performance and reliability of railway vehicles, they must be carefully considered when selecting bearing solutions. Drive systems for railway trains, such as gearboxes or traction motors, must be powerful, sustainable, cost-effective and require minimal maintenance. As maintenance intervals become increasingly longer and the weight of railway rolling stock continues to rise, these requirements are becoming ever more critical.

Motors must deliver high rotational speeds and withstand impact loads, whilst also withstanding low-load conditions, such as during coasting or cruise control modes. Furthermore, sensitivity to electrical discharge presents unique design challenges for motor bearings. All of these factors place high demands on bearing configurations. Specific challenges include a wider operating temperature range, high impact loads, and an increase in the overall load in conjunction with the drive system to reduce friction within the gearbox and lower energy consumption. We offer a range of solutions designed to help ensure reliable and cost-effective operations, whilst improving the efficiency and reliability of your fleet.
