Sell bearings of large sizes and weights A spherical roller bearing is a rolling bearing that can rotate with a low coefficient of friction and allows angular displacement Typically these bearings support a rotating shaft in the bore of the inner ring which can be displaced relative to the outer ring

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
