1. Poor bearing lubrication
When the bearing is running in a lean state, it is easy to cause adhesive wear and deteriorate the working surface. The tears produced by the adhesive wear are easy to enter the holding frame, causing abnormal load on the holding frame, and possibly causing the holding frame to break.
2. The phenomenon of bearing creep
Creep refers to the sliding phenomenon of the ferrule. In the case of lack of interference on 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 housing in the circumferential direction.
3. Abnormal load of bearing holder
Inadequate installation, tilting, excessive interference, etc. can easily cause reduced clearance, aggravate friction and heat generation, soften the surface, and exhibit abnormal peeling prematurely. As the peeling expands, the peeled foreign matter enters the holder pocket hole, causing the holder The operation is blocked and additional load is generated, which aggravates the wear of the cage. Such deterioration of the cycle may cause the cage to break.
4. Material defects of bearing holder
Cracks, large dissimilar metal inclusions, shrinkage holes, air bubbles and riveting defects, missing nails, pad nails or separation gaps between the two halves of the holding frame, severe riveting, etc. may constitute a holding frame fracture.
5. Intrusion of bearing hard foreign bodies
The intrusion of foreign hard foreign objects or other impurities will aggravate the wear of the holder.
6, the holding frame is damaged
The main reasons for the damage are: the holding frame vibrates too fast, wear and foreign matter blockage.
7. Persistent wear
The wear of the holder may be caused by lack of lubrication or abrasive particles.
8. The raceway is blocked by foreign matter
Fragments of flake materials or other hard particles may enter between the holder and the rolling element, preventing the latter from rotating around its own axis.
9. Bearing vibration
When the bearing vibrates, the inertial force can be so large that it can cause fatigue cracks, and these cracks will cause the holder to break sooner or later.
10. The bearing rotation speed is too fast
Assuming that the bearing runs beyond the design speed of the cage, the inertia encountered in the cage may cause the cage to break.
If you want the bearing holder to have a longer service life
