A major factor that the small ball bearing becomes application limits is wear. The wear occurs because of slipping caused in the bearing at low load. This slipping is called 'orbital slip'. The purpose of this research is to experiment on and quantitatively clarify the orbital slip. As a result of the experiment, the generation of orbital slip was confirmed. Moreover, quantitative data of orbital slip that has not been researched up to now was obtained for the first time. The tendency to orbital slip guessed from this experiment is shown as follows. 1) Orbital slip is generated easily by the rotational speed high and the load low. 2) Standard product slips than high accuracy product when a proper load hangs to the bearing.
