[0002] Bearings are important and key basic components in the equipment manufacturing industry. They directly determine the performance, quality and reliability of major equipment and host products. They are known as the "heart" components of equipment manufacturing. Deep groove ball bearings are suitable for high-speed or even extremely high-speed operation, and are very durable and do not require frequent maintenance. Deep groove ball bearings mainly bear radial loads, and can also bear radial loads and axial loads at the same time. When it only bears radial loads, the contact angle is zero.

[0003] At present, most of the internal balls of deep groove ball bearings will generate high temperatures during long-term use. If the internal temperature is not cooled down in time, the bearing will be deformed due to high temperature, affecting the reliability and service life of the bearing in the later stage. In addition, most of the existing bearings are not sealed on the outside. Dust contained in the air will enter the bearing in the later stage, increasing the wear performance of the bearing in the later stage, further reducing its service life in the later stage.
