The cleanliness of the bearing is an assessment index of the bearing quality, which must be guaranteed by the cleaning quality of the production process. The improvement of cleaning quality requires not only strict production management, but also the application of advanced cleaning technology to meet the cleaning requirements of products. Wafangdian Jinrui introduced the cleaning process of rolling bearings, ball bearings and other bearings in detail.

At present, in the bearing industry, the main method of bearing cleaning is spray cleaning with gasoline or kerosene as the cleaning medium. This method not only has high cost, high labor intensity, low production efficiency, but also poor safety. More importantly, this cleaning method is difficult to meet the standard of bearing cleanliness. Seeking a safer, more economical and more efficient cleaning method is of great significance to the cleaning of bearing finished products.

The conventional cleaning methods of bearing parts include brushing, dipping, spray cleaning or high-pressure spray cleaning, etc. The relevant factors are mainly the performance and usage requirements of the cleaning agent (ultrasonic cleaning can be used), the structure, size, weight and material of the workpiece. As well as batch size, labor safety and environmental protection requirements for cleaning workplaces. As an excellent new process, ultrasonic cleaning has been paid more and more attention in the bearing industry.

The cleanliness of the rolling bearing has a great influence on its vibration, noise, abnormal sound and service life. Especially in the production of small low noise deep groove ball bearings, improving the cleanliness is one of the keys to solving the bearing noise and abnormal noise, so the cleaning process is a very important part. Bearing cleaning is generally divided into two steps in the production process, that is, cleaning of parts (ferrules, steel balls, retainers, etc.) before assembly and cleaning of finished products after assembly and riveting.

The cleaning quality of the bearing is checked by hand. After the bearing is cleaned, carefully observe that there will always be some residual oil in the inner and outer ring raceways, on the rolling elements and in the gap of the cage. During inspection, you can first scrape out the remaining oil with a clean feeler gauge, apply it to the thumb, and slowly rub it back and forth with the index finger. Finally, hold the bearing in your hand, pinch the inner ring, and turn the outer ring to rotate horizontally (large bearings can be placed on the assembly table, the inner ring is gasketed, the outer ring is suspended, press the inner ring, and rotate the outer ring) to rotate Flexible, non-blocking, and non-beating are qualified.

For the cleaned bearing, after filling with lubricant, it should be placed on the assembly table, with a clean cloth or paper pad underneath, and a plastic sheet on the top, ready for assembly, and it is not allowed to be placed on the ground or box. When moving the bearing, it is not allowed to directly hold it by hand. You should wear canvas gloves or wrap the bearing with a clean cloth before taking it. Otherwise, due to sweat and moisture on your hands, it is easy to cause fingerprint rust on the bearing after contact.
