Flanged miniature bearings with EXTENDED Inner Ring
STAINLESS STEEL AISI440C
INCH sizes

These inch sized flanged miniature bearings have an inner ring that is wider than the outer ring by a total of 0.0312" (0.0156" on each side). The wide inner ring eliminates the need for spacers or washers. These stainless steel extended inner ring bearings have a stainless steel flange on the outer ring. This allows the bearing to be more easily located in a housing and can help to prevent axial movement in the event of a thrust load on the bearing.

It is easier to maintain the position of a flanged bearing in the housing where a lot of vibration is present. Flanged bearings are sometimes used where the housing is made from a different material and may expand more than the bearing outer ring at higher temperatures.
