NIIN 00-027-4028 - Airframe Ball Bearing

NSN 3110-00-027-4028 Classification

A cylindrical item in which the inner or outer ring turns upon row(s) of hardened ball, bearing which roll on a raceway, thus minimizing friction. These items are characterized by their noncorrosive qualities, lightness of weight, inch dimensions rather than metric, inner rings generally projecting beyond the faces of the outer ring, or a very narrow width inner ring having an outside diameter slightly larger than the bore diameter. Designed primarily for use in aircraft assemblies, such as control systems and surfaces of aircraft. Excludes:bearing,ball,annular.

0.4060 inches nominal inner ring width, 0.6250 inches nominal bore diameter, contact bearing seal type, radial load direction, mil-g-81322 mil spec single material response lubrication material document and classification

Hazmat, Precious Metals, Criticality, Environment, and ESD

A
(PMIC) Precious Metals Indicator
Item does not contain precious metal.
What does the A code means?

Precious metals indicator code (pmic): this code is to identify items that have precious metals as part of their content. Precious metals are those metals generally considered to be uncommon and highly valuable which are relatively superior in certain properties such as resistance to corrosion and electrical conductivity. The precious metals recovery program for the federal government encompasses gold, silver, platinum, and the platinum family which consists of palladium, iridium, rhodium, osmium, and ruthenium. See volume 10, table 160 and quick info on-line.

N
(HMIC) Hazardous Metal Indicator
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
What does the N code means?

Hazardous materials indicator code: a code established in the dlis total item record (tir) to identify to users of the federal catalog system all known or suspected hazardous items as defined by safety/health, transaction and/or environmental regulations, to serve as a flag that a procuring activity must acquire a material safety data sheet when a hazardous item is procured, and to inform federal catalog system users when more detailed information on an item is available in the hazardous material information system. See volume 10, table 179 and quick info on-line.

X
Criticality Code
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
What does the X code means?

Criticality code, federal item identification guide: a code which indicates when an item is technically critical, by reason of tolerance, fit, application, nuclear hardness properties or other characteristic which affects identification of the item. See volume 10, table 181 and quick info on-line.
