The invention discloses an improved ultrasonic cleaning process for a bearing ring, and relates to an improved ultrasonic cleaning process for a bearing ring. The problem that residual quenching salt exists after an existing bearing ring is subjected to ultrasonic cleaning is solved. The improved ultrasonic cleaning technology for the bearing ring comprises the following steps that the bearing ring is taken out of a quenching salt tank, then air cooling is conducted, the bearing ring is transferred to a cleaning tank through a transfer table, ultrasonic cleaning, clean water cleaning and deep cooling clean water cleaning are conducted in sequence, and then the bearing ring is preferably put into a tempering furnace to be subjected to tempering treatment. The process is improved, and the water temperature of the ultrasonic cleaning tank is increased from about 50 DEG C to 59-61 DEG C, so that the ultrasonic cleaning effect is improved, residual salt attachment is reduced, the recovery rate of salt for quenchin
