Usually, if accurate use bearings, can be used to achieve fatigue life to stop.However, JDB steel - copper inlaid bearing may be damaged unexpectedly and prematurely.This early damage, as opposed to fatigue life, is referred to as a failure or incident of quality transport JDB cast iron insert bearing with limit.Due to the device, use, lubrication on the attention, from the external invasion of JDB steel embedded bearing into the foreign body, on the shaft, the shell of the thermal impact of the study is not sufficient.
For the bearing damage, such as: roller bearing ring, retaining damage, as a factor can be considered, the lack of lubricant, not suitable, oil supply and discharge structure defects, foreign body invasion, bearing device error, shaft deflection is too large, there will be these factors overlap.
Therefore, it is difficult to know the real factors of bearing damage by only investigating bearing damage.But, if knew the use machinery of entrance bearing, use a condition, the structure around bearing, the state before and after understanding incident break out, the damage state that contacts bearing and a few kinds of factors investigate, can prevent similar incident to break out again.
