Even when bearings are used under normal conditions, the rolling surfaces of the bearing rolling elements are repeatedly subjected to compressive stress, which causes peeling due to material fatigue, making them unusable.

The so-called bearing life refers to the total number of revolutions until peeling occurs on the raceway and rolling surfaces. In addition, phenomena such as burning, wear, fracture, seizing, and rust can also render bearings unusable, but these are classified as bearing failures and are distinct from the definition of service life.

Errors in bearing selection, poor installation, improper lubrication, inappropriate clearance, and poor sealing performance are all causes of premature bearing scrapping. By comprehensively considering these factors, bearing failures can be avoided and their service life can be extended.
