Subject area	Mechanical engineering
More specific subject area	Vibration, machine condition monitoring
Type of data	.mat file
How data were acquired	An accelerometer was used to collect the vibration data and an incremental encoder was used to collect the rotational speed data
Data format	Raw
Experimental factors	Two experimental settings: bearing health condition and varying speed condition
Experimental features	Both bearing health condition and varying speed condition will change the frequency characteristics of the bearing vibration data
Data source location	Ottawa, Canada
Data accessibility	Mendeley Data.http://dx.doi.org/10.17632/v43hmbwxpm.1
