Flanged Miniature Bearings with Extended Inner Ring

Stainless steel flanged miniature bearings with extended inner ring for shaft sizes from 0.0469" to 0.3125"
See product table below for dimensions and technical drawings
See Products Variants below for non-flanged options

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.

EZO flanged stainless steel instrument bearings are made from KS440 stainless steel, also known as ACD34 or X65Cr13. This grade of stainless steel has a greater load capacity than AISI-440C grade and better low noise qualities. It is also has better corrosion resistance. These bearings, with a stainless steel retainer and a suitable high temperature lubricant, can be used at temperatures of 250°C constant or up to 300°C intermittent. Above these temperatures, the load capacity of stainless steel is reduced.

Click on INFO in the rows below to display technical drawings of the bearings with load and speed data. The load ratings shown are for AISI-440C flanged bearings. Load ratings are higher for EZO KS440 bearings. Please note that the maximum loads and speeds are used in theoretical life calculations. It is recommended to use bearings at significantly less than the maximum load and speed ratings to ensure reasonable bearing life.
