Why is bearing damage
only part of the bearing damage in practical applications? Most bearing applications are over the life of machine or device itself. Bearing damage is for many reasons - beyond the original estimate of the load, or non-effective tight seal with the result of too small bearing clearance and so on. Any one factor has its particular damage type and will leave special signs of damage. Therefore, the view will damage the bearing can be found in most cases because of the possible lead, and based on these findings, the measures taken to prevent recurrence.
Generally speaking, one-third of the bearing causes damage based on fatigue damage, the remaining third reason is that poor lubrication, and other contaminants into the bearing of one-third of improper handling or installation.
However, these types of damage are associated with different industries. For example, pulp and paper industry is mostly due to poor lubrication or contamination caused by bearing damage and not due to material fatigue caused.

With the right knowledge and tools for installation techniques to ensure the bearings from damage
the beginning of the bearing damage
Bearing from getting started to a fatigue phenomenon is the length of the period and the number of revolutions of the bearing, load size, the degree of lubrication and clean. Fatigue is the shear stress under the load surface periodicity formed by the results. Over time, these shear stresses will lead to small crack Lu, and then gradually extend to the surface, when scrolling through these pieces of crack Lu, they block off some crack to form a so-called peeling phenomenon. Then continue to expand as the peeling of the situation, bearing that is damaged and unusable. The above is a description of fatigue; in the first place it is located below the surface.
Although the initial peeling usually is very mild, but with the increase in stress and crack the block increase, leading to the spread of peeling area, this type of damage process usually last a long time, the stage is visible in the increase when the voice and vibration.
