What is the reason for the bearing cage to break?

A bearing cage failure can lead to various issues, including increased friction, noise, and ultimately the failure of the bearing itself. Several reasons can contribute to the breakage of a bearing cage:

1.Material Fatigue: Over time, the constant cyclic loading and unloading that bearings experience can lead to material fatigue in the cage. This is especially true if the cage material is not properly selected or if the bearing is subject to heavy loads or high-speed rotations.

2.Excessive Load or Speed: If a bearing is subjected to loads or speeds beyond its design limits, it can lead to increased stress on the cage. This stress may exceed the material's strength, causing the cage to deform or break.

3.Improper Installation: Incorrect installation of bearings can result in misalignment, which puts additional stress on the cage. It's essential to follow the manufacturer's recommendations for proper installation procedures.

4.Contamination: Presence of contaminants such as dirt, debris, or abrasive particles within the bearing can accelerate wear on the cage. This increased wear may weaken the cage structure over time, leading to breakage.

5.Insufficient Lubrication: Inadequate lubrication can result in increased friction and heat generation within the bearing. This can lead to accelerated wear on the cage, making it more prone to failure.

6.Corrosion: Exposure to corrosive environments can lead to the degradation of the cage material, reducing its strength and increasing the likelihood of breakage.

7.Design Issues: In some cases, the design of the bearing cage may be inadequate for the specific application or load conditions. Poor design choices, such as using an inappropriate material or geometry, can contribute to cage failure.
