Four-point error separation method is further explained by Tiainen & Viitala (2020). Data taken from channel 1 of test 1 from 12:06:24 on 23/10/2003 to 13:05:58 on 09/11/2003 were considered normal. Description: At the end of the test-to-failure experiment, inner race defect occurred in bearing 3 and roller element defect in bearing 4. The data was generated by the NSF I/UCR Center for Intelligent Maintenance Systems (IMS - www.imscenter.net) with support from Rexnord Corp. in Milwaukee, WI.
