Data for: Advance spectral approach for condition evaluation of rolling element bearings

The bearing signals are extracted by PCB 608A11 piezoelectric ICP Accelerometers attached over the bearing case and a NI cDAQ-9234 data acquisition system. Provision of NI Lab VIEW software with the DAQ facilitates in data acquisition. The vibration signal is collected after every 10 minutes of operation with a sampling rate of 25.6 kHz and signal length of 2560 (corresponding to 0.1 sec). The failure time for bearing B1 which is considered for further investigation is recorded to be12250 minutes in test one and that of the bearing B2 is 14990 minutes in test two.

轴承信号由安装在轴承座上的PCB 608A11压电式ICP加速度传感器（piezoelectric ICP Accelerometers）与NI cDAQ-9234数据采集系统采集获取。搭配NI LabVIEW软件的该数据采集系统可高效完成数据采集流程。本数据集每运行10分钟采集一次振动信号，采样率为25.6kHz，单条信号长度为2560（对应时长0.1秒）。本次研究后续将重点分析的轴承B1与轴承B2的失效时间分别为：试验1中轴承B1的失效时间为12250分钟，试验2中轴承B2的失效时间为14990分钟。
