Abstract
The present ball/roller bearing cleaning method is a method which, using cleaning liquid , cleans a bearing to be cleaned composed of an inner ring , an outer ring , a rolling bodies and a retainer. In the cleaning method, the cleaning liquid is made to flow through the bearing to be cleaned from the axial direction of the present bearing into spaces in which the raceway surfaces of the inner and outer rings and of the bearing to be cleaned surround the rolling bodies and retainer. For example, a cylindrical-shaped rotary die having spiral grooves is interposed into a cleaning liquid supply passage, and the cleaning liquid is supplied to thereby rotate the cylindrical-shaped rotary die , whereby the cleaning liquid having high pressure can be supplied to the bearing to be cleaned from the cylindrical-shaped rotary die
