Needle bearing endurance test data for early fault detection

This dataset contains experimental run-to-failure data of oscillating needle bearings. For each experiment, two bearings were tested. In total, eight tests were conducted, in which the test parameters such as lubrication, sine wave amplitude, preload and frequency were varied. The following were recorded: Acceleration Radial bearing movement Torque Temperature Radial load Amplitude of the oscillation The dataset is stored in a standard MATLAB ‘.mat’ file, which consists of a matrix with the first column being a time vector (in seconds) and the second column corresponding to raw sensor data. The filename for each dataset follows the following format Test2_Oil2_10-9-10_Data_1_to_1032_Acc_Sensor_1.mat: Test Number (1-8) Lubrication Test Parameters (Amplitude [deg]-Radial Load [kN]-Frequency [Hz]): Measurement data number Sensor with the Sensor Position (suffix_1 at needle bearing_1 and suffix_2 at needle bearing_2)
