Abstract:
1. A rolling bearing cleaning method for cleaning a bearing by using a cleaning liquid, the rolling bearing including an inner ring, an outer ring, rolling elements and a retainer, comprising steps of: immersing the rolling bearing in the cleaning liquid, which is disposed in a cleaning vessel; fixing one of the outer ring and the inner ring, and disposing the other ring so as to be free to rotate while disposing the rolling bearing to be cleaned near a surface of the cleaning liquid; flowing the cleaning liquid such that cleaning liquid flows through the rolling bearing from the axial direction of the rolling bearing into spaces existing between raceway surfaces of the inner and outer rings and surrounding the rolling elements and the retainer; cleaning the rolling bearing by flowing the cleaning liquid through an inner portion of the rolling bearing without rotating the same; and cleaning the rolling bearing by flowing the cleaning liquid through an inner portion of the rolling bearing while rotating the same, via the cleaning fluid, after execution of the non-rotation cleaning step.
