What must be attached to a bearing during inspection?

During the inspection of a bearing, it is essential to attach a hot box tag. This tag serves as a critical indicator of the potential overheating of a bearing, which can pose a serious risk during rail transport. The presence of a hot box tag alerts maintenance and engineering personnel to the need for immediate attention and further evaluation to ensure the safety and reliability of rail operations.

The hot box tag provides specific information regarding the condition of the bearing, documenting any abnormal temperatures detected during inspections. This is crucial for timely intervention, which can prevent further damage or operational failures. Assigning this tag to the bearing helps maintain operational safety and efficiency within the rail network, ensuring that all personnel are aware of the condition of the equipment.

While an inspection report and a maintenance checklist can be important for overall equipment management, they do not carry the urgent and specific warning that a hot box tag provides. Additionally, a warning sign, while useful in various contexts, does not convey the necessary detailed output specifically related to bearing inspection results.
