Group 31 of the FSG groups a part of the NSN number is created by bearings. Different subcategories of bearings are separated due to different types designs, lubrications and/ or selected.

Federal supply code group which contain following supply codes:

Commencing with the 3110 Group which include 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.

Followed by the 3120 subgroups which includes primarily bearings with “one piece” that hold or position moving parts. Often these one-piece bearings come pre-lubricated in their grooves, fittings, and facilities. These bearings include Sleeve Bearings; Split Bearings; Washer Type Bearings; Jewel Bearings. This group omits Antifriction Bearings (FSC 3110) and Mounted Bearings (FSC 3130).

The last of the 31 family includes the 3130 group which includes Bearings, Mounted. Much like the 3010 group this subgroup includes bearings with confined a ring to decrease friction in/on/around apparatuses. The group includes Pillow Block Units; Cartridge Units, Flange Units, Take up Units, Hanger Box Units, Flat Box Units, and Step Box Units. They strictly exclude Antifriction bearings (FSC 3110) and Plain Unmounted Bearings (FSC 3120).
