Why did the bearing fail after just a few days of replacement?

[CourtneyMarie]

The reason why the bearing failed after just a few days of replacement is that when replacing the bearing with a different supplementary code, the outer ring was not replaced at the same time. Here is some relevant information about bearings: 1. Introduction to bearings: Bearings are an important component in contemporary mechanical equipment. Their main function is to support the rotating body of the machinery, reduce the friction coefficient during its movement, and ensure its rotational accuracy. 2. Bearing life: Under a certain load, the number of revolutions or hours that a bearing undergoes before pitting occurs is called the bearing life. Due to differences in manufacturing precision and material uniformity, even bearings of the same material and size from the same batch may have different lifespans under the same working conditions.
