Hi Vidya,

How many months before the previous failing of inner race was? do you have any monitoring device or just a scheduled monitoring?

in my previous experience, we get this inner race failure when bearing fit and clearance was not achieve.

regards,

Hi RG,

          previous failure was 2 years back and we use SPM instrument for condition monitoring.Does fitment and clearance is the cause for three failures??

Any Problem due to load ???

Vidya,

how much is the amount of impacting before this happen? is there a temperature increase before? after that crack when you ovehaul, did the inner race spun on the shaft?

regards,

RG,

       There is no significant increase in temperature and yes inner race spun on shaft.

i didn't get what exactly impacts u are asking,whether the load or in TWF??

Measure the bearing fit on the shaft, maybe it's way over sized.

Im just curious that this is sudden failure or the failure developed? i doubt at the data collection since this is not sees that will generate fault.
