1, vibration
When the SKF bearing is under shock conditions, SKF bearing internal forces may cause fatigue cracks at the cage. Gradually, this crack will break the retainer. To prevent this behavior, SKF bearings can be equipped with a special cage.
2, faster than the design requirements
SKF bearings are faster-than-keep the material can bear run, inertial forces will lead to a cage rupture. High-speed SKF bearings manufactured specifically for such occasions.
3, wear
Improper lubrication or solid foreign bodies make SKF bearing retainer wear. SKF bearings running while scrolling the bogey slide friction. Sliding contact between roller and retainer is usually cannot be removed, so if the poor lubrication, and wear parts of the cage were the first. And holder are made of a soft texture of materials, so wear and tear is fairly quick. Come to retainer clearance will break the cage quickly. When hard particles into SKF bearings, also has the same condition.
4, foreign object stuck
Part of fragments or particles may be stuck in cage-free and between the rollers. Impede the scroll scroll. It also leads to keep breaking. As long as they can prevent large foreign bodies penetrated SKF bearing, even heavy loads of occasions, cage can be safe.
