Abstract
The present ball/roller bearing cleaning method is a method which, using cleaning liquid, cleans a bearing to be cleanedcomposed of an inner ring, an outer ring, a rolling bodiesand a retainer. In the cleaning method, the cleaning liquidis made to flow through the bearing to be cleanedfrom the axial direction of the present bearinginto spaces in which the raceway surfaces of the inner and outer ringsandof the bearing to be cleanedsurround the rolling bodiesand retainer. For example, a cylindrical-shaped rotary diehaving spiral groovesis interposed into a cleaning liquid supply passage, and the cleaning liquidis supplied to thereby rotate the cylindrical-shaped rotary die, whereby the cleaning liquid having high pressure can be supplied to the bearing to be cleanedfrom the cylindrical-shaped rotary die
