This study presents a frequency-band subspace-based damage identification method for faults diagnosis in roller bearing. The main purpose is to obtain damage sensitive indicators in the frequency range where a damage is expected to appear. The proposed method is validated using the data collected from bearing run-to-failure tests. It is shown that the proposed method can detect bearing defects at an early stage of development and appears therefore as an efficient tool for diagnosis purposes.
