Bearing size

Therefore the two main criteria that can be used for determining appropriate bearing size are: Size selection based on rating life: This is based on the required bearing life taking into account the possible effects of rolling contact fatigue and requires calculation of the basic rating life L 10 or QIBR rating life L 10m for the bearing Size selection based on static load: This is based
