In general, if the proper use of deep groove ball bearings can be used up to its maximum life. If not used correctly it will have an unexpected premature damage. Such fatigue life and relatively early damage, failure or accident we call the quality of use limits. More due to the installation, use, lubricate the non-standard, or invasion of foreign matter from the outside.
Damage on the state, such as deep groove ball bearings: bearing rings, ribs card injury, mainly due to lack of lubricant, not suitable for oil discharge structure defects, invasion of foreign substances, flexural bearing misalignment, shaft It is too large, or both the above reasons.
Thus, the survey only bearing damage, it is difficult to know the real cause of injury. However, if you know the mechanical conditions of use, the bearing structure around the bearings, to understand the situation before and after the accident, combined with state of the bearing and damage several reasons, it can prevent similar incidents from recurring.
Deep groove ball bearing vibration of the bearing damage is very sensitive, such as peeling, indentation, corrosion, cracks, wear, etc. will be reflected in the rolling bearing vibration measurement, so, through the use of special bearing vibration measuring device (frequency analyzer, etc.) can measure the size of the vibration frequency points can not be inferred unusual circumstances. The measured values due to the conditions of use or sensor installation location of rolling bearings, etc., and thus requires prior measurement value each machine is determined after analysis and comparison criteria.
Deep groove ball bearing temperature, generally bearing chamber outside temperature can be inferred, the hole can also be used to directly measure the temperature of the rolling bearing outer ring, which is a more accurate measurement.
