1. Poor lubrication of deep groove ball bearings
The bearing is running in a lean state, which is easy to form adhesive wear, which will deteriorate the working surface. The tears generated by the adhesive wear will easily enter the cage, causing abnormal load on the cage, and possibly causing the cage to break.
2. Creep phenomenon of deep groove ball bearings
Creep refers to the sliding phenomenon of the ferrule. In the case of insufficient interference of the mating surface, the load point moves to the surrounding direction due to the sliding, which causes the ferrule to deviate from the shaft or the housing in the circumferential direction.
3. Intrusion of hard foreign bodies in deep groove ball bearings
The intrusion of foreign hard foreign objects intensifies the wear of the cage and generates abnormal additional loads, and may also cause the cage to break.
4. Material defects of deep groove ball bearing cage
Cracks, large dissimilar metal inclusions, shrinkage holes, bubbles and riveting defects, missing nails, pad nails or gaps between the two cage halves, serious damage, etc. may cause the cage to break.
5. Abnormal load of deep groove ball bearing cage
Inadequate installation, tilting, excessive interference, etc. will easily reduce the clearance, increase friction and heat generation, soften the surface, and cause abnormal peeling early. As the peeling expands, the peeled foreign objects enter the cage pockets, resulting in the cage The operation is blocked and additional load is generated, which intensifies the wear of the cage. Such a worsened cyclic effect may cause the cage to break.
