1. A sensor roller for a roller bearing, the sensor roller comprising:
a measuring unit for measuring at least a temperature, a speed change, and a load of the roller, wherein
the sensor roller comprises a processing unit for generating a temperature profile, a speed change profile and a load profile of the roller based on the measured temperature, speed change and load, wherein
the sensor roller further comprises a memory unit that stores temperature profiles, speed change profiles, and load profiles of the roller, wherein
the processing unit is configured to compare the generated temperature profile, the generated speed change profile, and the generated load profile with the stored temperature profiles, the stored speed profiles, and the stored load profiles, and wherein
the processing unit is configured to update the stored temperature profiles, the stored speed change profiles, and the stored load profiles based on the comparison to the generated temperature profile, the generated speed change profile and the generated load profile.
