What causes bearing failure?

The current market demand for bearing seats is high, which is often accompanied by some bearing failures. Most of the failure modes are wear life, abrasion life, fatigue life and lubrication life, etc. These are calculated and calculated based on the corresponding data. Evaluated.

Regarding the four different failure modes of mounted bearings:

1. Wear life: Bearings and bearing seats produced and provided by factories are generally matched. Mechanical equipment is used with bearing seats. Under long-term operation and use, but before complete fatigue is reached, wear and tear often occurs. The problem causes its accuracy to be unable to be used continuously. In reality, many bearing seats fail due to excessive wear and cannot be used.

2. Abrasion life: Bearings generally used on large mechanical equipment will also suffer fretting abrasion damage due to oscillating loads in non-working conditions. This is also the main reason for the failure of the bearing seat.

3. Fatigue life: If the bearing seat is found to have failed when the lubrication conditions are normal, it may be due to excessive fatigue due to use. Its service life can be queried according to the sample, and it can also be queried according to the formula. calculated.

4. Lubrication life: For double-sided sealed grease bearings, after filling, there is no need to add more grease. At this time, it depends on its service life.

The cause of bearing failure is often caused by a variety of factors. Some factory operations during the design and manufacturing process are inappropriate, or there are design problems. These factors will be related to bearing failure. Therefore, when we start designing and manufacturing bearings, we focus on these reasons and pay attention to our own operating methods, so as to avoid various problems when the bearings are used in the later period.
