X conducts locomotive maintenance through workshop to ensure the reliability and safety of railway operations. As a component related to wheel propulsion, the maintenance of tapered roller bearings on locomotive bogies is critically important. Located on the outer side of the wheel assembly, these tapered roller bearings function to support both axial and radial loads exerted by the locomotive. Calculating the bearing lifetime is essential to determine its operational duration, thereby enabling the company to perform scheduled bogie maintenance in accordance with work instructions. Bearing lifetime directly affects maintenance effectiveness and the overall maintenance cost.
