National Stock Numbers are 13-digit numeric codes assigned to all items that are procured, stocked, and distributed by the federal supply chain. The 13-digit code can be split into various subcategories:
Federal Supply Classification Group (FSCG) - The first 4-digits of the NSN. This is split into the FSG and the FSC.
Federal Supply Group (FSG) - The first 2-digits of the NSN.
Federal Supply Classification (FSC) - The second 2-digits of the NSN

The Federal Supply Codes within FSG 31 that we supply include:
Includes Ball Bearings; Roller Bearings; Balls; Races and exclude the Plain Bearings (FSC 3120); Jewel Bearings (FSC 3120). These particular bearings are mostly confined by a ring to decrease friction between the rotating machinery.

These bearings include Sleeve Bearings; Split Bearings; Washer Type Bearings; Jewel Bearings. This group omits Antifriction Bearings (FSC 3110) and Mounted Bearings (FSC 3130).
