The function of the ball cage dust jacket is to wrap the grease, prevent the grease from flowing out of the ball cage, and keep the lubrication inside the ball cage. Once the dust jacket is broken, the grease will be lost, and dust and soil will enter the bearing of the ball cage, resulting in abnormal wear of the ball cage, and even stuck. Therefore, the dust jacket plays an important role in protecting the ball cage components
The working principle of the cage dust jacket is to prevent dust and moisture from entering the inside of the cage through its material characteristics (such as the dual characteristics of rubber and plastic), while maintaining the internal lubrication. When the dust jacket is broken, the grease will be lost, resulting in excessive wear of the ball cage components due to lack of lubrication, which may eventually lead to component damage. Therefore, once the dust jacket is found to be damaged, it should be replaced in time to avoid more serious damage
