For bearing cages, fracture is the most troublesome opinion. Therefore, according to the understanding to tell you about the common factors of bearing cage fracture, understanding these, can make everyone better maintenance when using the bearing cage, so that the bearing cage life is longer. Grasp these ten points to ensure a longer service life of the bearing cage-common factors for bearing cage fracture:

1. Poor bearing lubrication

The bearings are running in a lean state, and it is easy to form adhesive wear, which deteriorates the state of the working surface. The tears caused by adhesive wear easily enter the cage, causing the cage to generate an abnormal load, which may cause the cage to break.

2. Bearing creep phenomenon

The creep phenomenon of multi-finger ferrule, when the interference of the mating surface is insufficient, the load point moves to the surrounding direction due to sliding, resulting in the phenomenon that the ferrule moves relative to the shaft or the shell in a circumferential direction.

3. Abnormal load of bearing cage

Insufficient installation, tilt, excessive interference, etc. can easily cause clearance reduction, exacerbate friction and heat, soften the surface, and abnormal peeling occurs prematurely. As the peeling expands, peeling foreign objects enter the pockets of the cage, leading to the cage The operation is retarded and additional load is generated, which aggravates the wear of the cage. Such deterioration of the cycle may cause the cage to break.

4. Defective material of bearing cage

Cracks, large foreign metal inclusions, shrinkage holes, air bubbles, and riveting defects are missing nails, pad nails, or gaps in the joint surface of the two halves of the cage, and severe rivet injuries may cause the cage to break.

5.Intrusion of hard foreign matters in bearings

The invasion of foreign hard foreign matter or other impurities will aggravate the wear of the cage.

6, the cage is broken

The main causes of damage are: the cage vibrates too fast, wear and foreign bodies are blocked.

7, cage wear

Wear on the cage can be caused by insufficient lubrication or abrasive particles.

8, foreign body clogging on the raceway

Pieces of sheet material or other hard particles may enter between the cage and the rolling body, preventing the latter from rotating about its own axis.

9.Bearing vibration

When the bearing vibrates, the inertial force can be so large that it causes fatigue cracks, which sooner or later cause the cage to break.

10.The bearing rotates too fast

If the bearing runs faster than the design speed of the cage, the inertia experienced in the cage may cause the cage to break.
