An air blowing fan is mounted on a seating jig provided in a housing, an inlet of the air blowing fan is sealed with a sealing cylinder, the outer surface of the upper end of the air blowing fan is pressurized and fixed with a jig cylinder, the inlet of the air blowing fan is sealed with an ascending and descending sealing cylinder, the air pressure around an air supply pipe is measured with a pressure sensor while supplying predetermined pressure air into the air blowing fan through the air supply pipe of the ascending and descending sealing cylinder, to be transmitted to an identifying device, and the air pressure measured by the pressure sensor is calculated and compared with a first and a second reference pressure inputted into the identifying device to identify the kind of a bearing corresponding to the first and the second reference pressure. According to the present invention, the type of the bearing corresponding to the first reference pressure or the second reference pressure can be identified by calculating and comparing the air pressure around the air supply pipe measured by the pressure sensor with the first reference pressure or the second reference pressure of the identifying device. Owing to the identification of the kind of the bearing, whether or not a bearing required by a company has been installed in the air blowing fan can be checked easily. Moreover, the amount of gas leakage through the bearing can be checked while measuring a change in the air pressure around the air supply pipe in real time, and the value of the air pressure measured by the pressure sensor can be checked to determine whether the bearing has been incorrectly assembled or whether the bearing is defective. The defect and kind of the bearing in the air blowing fan can be determined simultaneously to increase work efficiency while reducing a product inspection time, thereby improving the reliability of products.
