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.
Packing shall be accomplished in accordance with table c.ii for the packing level specified. closure, sealing and reinforcement shall be in accordance with applicable specification for shipping container.
Packing shall be accomplished in accordance with table c.ii for the packing level specified. closure, sealing and reinforcement shall be in accordance with the appropriate shipping container specification.
Options can be exercised as to specific method of preservation or dod approved packaging materials to be used. however, basic preservation method shall be retained, supplemental data shall be complied with, and unit package dimensions shall not be increased by more than one inch. equal or better protection shall be given the item and there shall be no increase in the package cost.
No special marking.
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.

SOS: Source of Supply. A three position code or routing identifier code (ric), which identifies the source of supply activity.
SMIC: Special Material Indicator Code. A two position code, which categorizes material on the basis of requirements for source or quality control, technical design or configuration control, procurement, stocking and issue control, special receipt, inspection, testing, storage, or handling.
MMAC: Material Management Aggregation Code. A two position code that identifies an item of supply to be managed by a specific activity manager.
MCC: Material Echelon Code. A two position code employed by the marine corps in classifying items into categories by materiel category and procurement echelon. the alphanumeric management code is in the first position and identifies the materiel category
IMC: Denotes wether items shall be subjected to integrated management under the defense supply agency or retained by the individual military service or other department of defense components for their management. Assigned by th activity responsible for item management coding.
