The common failure modes in the operation of stainless steel bearing seats are as follows:
1. Exhausted shedding
On the surface of the dovetail guide rail or inside the flipped body of the flipped inlet bearing, due to the effect of alternating load changes, the metal material on the surface falls off and slowly expands, resulting in dents. If operated again, there will be areas of detachment. Due to poor installation or misaligned bearing holes with seats and shaft axes, some positions of rolling bearings may bear a significant load, resulting in initial fatigue and ineffectiveness.
2. Gaps and cracks
Defects in raw materials, thermal negligence, excessive intervention, and poor composition design schemes, such as stress caused by support plate surface pipe grooves, all contribute to ring cracks and fractures.
3. Imprinting
When external hard particles enter the rolling bearing and press between the flipping body and the dovetail guide rail, the flipping surface can retract. In addition, excessive impact loads can also cause plastic deformation on the surface, resulting in dents. When the rolling bearing is stationary, even if the load is not large, the vibration of the surrounding environment will produce uniform indentations on the dovetail guide rail.
4. Damage
When the sealing performance of roller bearings is poor, dust or fine particles enter the rolling bearings or the lubrication is poor, it can cause serious surface damage or damage, increasing the vibration and noise of the rolling bearings.
5. Current etching
According to the current of the rolling bearing, small sparks may be caused, which may cause partial quenching and small dents or gray black repair on the surface of the contact. When it is more severe, deep pits may appear.
