This paper describes an investigation into squealing sounds which occur in the large-sized cylindrical roller bearing fitted into an annular housing by means of an interference fit. Squeals of approximately 5 kHz and 6 kHz occur at shaft speeds of 1000〜16000 rpm. These frequencies are not the natural frequencies of the in-plane vibration of the housing including the outer race regarded as a thick ring. Replacing the roller/outer race contact as a spring in loading zone and considering friction between the roller and the outer race, we calculated the natural frequencies of in-plane vibration of the ring coupled with the stationary roller. As a result, squeal frequencies almost agree with natural frequencies which indicate an oscillatory instability and are close to the natural frequency of a single roller.
