If on examination of a failed bearing, the cage is found to be damaged, it may oftentimes show difficult to ascertain the cause. Typically, other components of the bearing are harmed and this makes it tougher to find the factor for the trouble. However, there are particular main causes of cage failure, viz. resonance, warm excessive rate, as well as blockage.

- Wear and Clog
Pieces of spotted material or other difficult particles might become wedged between the cage and a rolling element, avoiding the latter from revolving around its own axis. This causes cage failure.
- Vibration
When a bearing is revealed to vibration, the pressures of inertia may be so wonderful as to trigger exhaustion cracks to create in the cage material after a time Sooner or later these splits cause cage fracture.
- Too much rate
If the bearing is gone for rates in excess of that for which the cage is developed, the cage is subjected to heavy pressures of inertia that may cause cracks. Regularly, where really broadband is entailed, it is possible to select bearings with cages of the special layout.
- Other root causes of cage damage
If the rings of a deep groove ball bearing are fitted out of placement with each other, the course of the balls has an oblong setup. If the cage is centered on the spheres, it has to transform shape for each revolution it carries out. Exhaustion fractures after that develop in the product, and sooner or later they result in fractures. There is a comparable instance when a drive ball bearing is fitted together with radial plain bearings. If clearance emerges in the ordinary bearings, the washing machines of the thrust bearing ended up being displaced in connection with each various other. Then the spheres do not follow their typical course and hefty tensions might occur in the cage.
