The basic group includes three sets of normal data and three sets of outer race fault data, collected under a load of 270 lbs, a shaft speed of 25 Hz, and a sampling rate of 97656 kHz. The extended group contains two variable-load subsets: seven sets of outer race fault data (collected at loads ranging from 25 to 300 lbs with a sampling rate of 48828 kHz) and seven sets of inner race fault data (collected at loads ranging from 0 to 300 lbs with with a sampling rate of 48828 kHz).
