Re: Bearing Life Expectancy


i am sharing you with my practical experience. 22 kw 2900 rpm motor of compressor runs 24 hrs and bearings got damaged after 3500 hrs.To save the motor from damage ,we inspect the bearings between 2800-3000 hrs and this is the stage from where he damage starts.On other hand,he bearings of slow speed motors runs between 8000-10000 hrs.
