QQ-B-626 fed spec single material response
plain round
An item designed to be mounted around a shaft to limit axial movement of the shaft and/or its assembled parts. It is secured directly to the shaft by use of a setscrew(s), pin(s), or the like, which may be a part of the item of supply. A pilot hole drilled in or through the wall(s) for drilling and pinning at application may be considered a method of securing. Solid items have a bearing surface on one or both end(s) perpendicular to the axis. For items designed to be mounted around the extended hub portion of a mounted item on a shaft or clamp around a shaft, see clamp, hub. See also bearing, sleeve; bushing, sleeve; spacer, sleeve; and coupling, shaft, rigid.
OPI: Optional Procedure Indicator Code. A one position alpha code that indicates the allowable deviations from the prescribed requirements.
SPI No.: Special packaging instructions number.
LVL A/B/C: Indicates the type of shipping container required for level A, B, or C maximum packing protection.
SPC Mkg: A two position code that identifies the special markings applied to the container, which is part of the total pack to protect the contained item during preservation, packing, storage, transit and removal from the pack.
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Precious metal content is unknown
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.
PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
