Precision Radial Bearing 1603

The Tritan SS3825 ZZ FM222 is a new 1603-series radial ball bearing built for inch-dimension shafts. It has a .3125 inch bore, a 7/8 inch outside diameter and a .281 inch outer ring width. Both rings and the cage are made from 304 stainless steel with double shields for contamination resistance.

Food-grade and chemical environments

This bearing suits equipment that must withstand chemical wash-downs, food-processing lines or pharmaceutical machinery where corrosion resistance matters. It is not intended for builders who need a flanged housing, a higher ABEC precision class or a larger bore diameter for heavier radial loads.

Press-fit installation notes

The bore tolerance of +0/- .0003 inch means a light press fit on a correctly sized shaft; forcing it can brinell the raceways. The double shields are not removable, so internal lubrication cannot be replenished after the factory fill.

Questions about this item

What shaft size does the .3125 in bore fit?

The bore diameter is 5/16 in with a tolerance of +0/-0.0003 in, so it fits a standard 5/16 in shaft.

Will the 7/8 in outside diameter and .281 in width match my existing 1603 housing?

Yes, the bearing follows industry number 1603 with a 7/8 in outside diameter and 0.281 in outer ring width, matching standard 1603 dimensions.

How can I confirm the double shields are seated correctly after installation?

The ZZ designation means double metal shields; after pressing the bearing into the housing, both shields should sit flush with the inner ring faces and rotate freely without contact.
