Condition Based Maintenance Fault Database for Testing of Diagnostic and Prognostics Algorithms

Data assembled and prepared on behalf of South Ural State University.

Bearing Fault Dataset

A bearing fault dataset has been provided to facilitate research into bearing analysis. The dataset comprises data from a bearing test rig.

The linear and angular signals of all five bearings were collected with a sampling frequency of 31.175 kHz with the system operating at 1200 rpm (i.e. at 20 Hz).

The data set comprises the following

• normal condition
• fault in inner race
• fault in outer race
• fault in ball
• combination fault

Note: The data is stored in a Matlab double-precision, binary format *.mat file. The data structure holds vectors of linear and angular acceleration data.
