FSC 3110: Bearings, Antifriction, Unmounted
Federal Supply Class (FSC) 3110 covers unmounted antifriction bearings, meaning ball and roller bearings supplied without a housing. These precision NSN items support rotating assemblies across the fleet.
Antifriction bearings reduce friction and support rotating shafts under radial and thrust loads. They are essential to smooth, efficient operation of machinery and engines.
Common types include ball bearings, cylindrical, tapered, and spherical roller bearings, and needle bearings. Bearings are made from hardened bearing steel and corrosion-resistant alloys to precise tolerances.
