Abstract Accurate fault diagnosis of rolling bearings under strong noise conditions remains challenging, as noise can significantly degrade feature quality. Although data-driven methods such as convolutional neural networks and Transformer-based models have shown strong feature extraction capabilities, their performance often deteriorates in low signal-to-noise ratio environments due to insufficient modeling of global correlations and loss of subtle fault-related information.
