The cage plays the role of isolating the rolling elements at equal distances and preventing the rolling elements from falling in the rolling bearing, guiding and driving the rolling elements to rotate. The first damage (failure) component of the bearing is often the cage. The cage can be said to be the "blood vessel" of the bearing. The inner ring, outer ring, and rolling elements can be evenly and orderly distributed. A slight error can easily make the bearing. The service life is greatly shortened or even damaged. Therefore, the maintenance of bearing lubricants is very important
What is the cause of the fracture of the bearing cage?
1. Insufficient bearing lubrication
2. Impact load of the bearing
3. Cleanliness of the bearing
4. Installation problems. Incorrect installation of the bearing will damage the cage during installation
5. Bearing creep phenomenon
6. Abnormal load of bearing cage
7. Material defects of bearing cage
8. Intrusion of bearing hard foreign bodies
9. Other reasons. If the coupling is misaligned, the bearing is skewed and the force is uneven; the belt is installed too tightly; environmental problems, etc., may damage the bearing or cage.
To solve the above reasons such as insufficient lubrication, the life of the bearing will be very long. However, it is recommended that the reasons for the damage of the bearing cage have to be analyzed in detail, depending on what type of bearing you are using, which equipment is installed on it, and what is the working condition.
