MFPT bearing dataset

Description: This dataset has been provided by MFPT and the original data source can be found at http://www.mfpt.org/FaultData/FaultData.htm .A bearing fault dataset has been provided to facilitate research into bearing analysis. The dataset comprises 7 sets of data. The first 4 sets of data come from a bearing test rig with: basline (good condition bearing), an outer race fault, outer race fault with various loads and inner race fault with various loads. The next 3 sets of data are from real-world faults, being from: an Oil pump bearing, Intermediate Speed bearing and a Planet bearing.
