Patent attributes
The present ball/roller bearing cleaning method is a method which, using cleaning liquid 24, cleans a bearing to be cleaned 1 composed of an inner ring 1b, an outer ring 1a, a rolling bodies 1c and a retainer. In the cleaning method, the cleaning liquid 24 is made to flow through the bearing to be cleaned 1 from the axial direction of the present bearing 1 into spaces in which the raceway surfaces of the inner and outer rings 1b and 1a of the bearing to be cleaned 1 surround the rolling bodies 1c and retainer. For example, a cylindrical-shaped rotary die 2 having spiral grooves 2a is interposed into a cleaning liquid supply passage, and the cleaning liquid 4 is supplied to thereby rotate the cylindrical-shaped rotary die 2, whereby the cleaning liquid having high pressure can be supplied to the bearing to be cleaned 1 from the cylindrical-shaped rotary die 2.
