Standard Specification for Annular Ball Bearings for Instruments and Precision Rotating Components

ABSTRACT
This specification covers annular ball bearings intended primarily for use in instrument and precision rotating components. Annular ball bearings for instrument and precision rotating components shall be of the following types, as specified: type I - deep groove, unflanged; type II - deep groove, flanged; type III - deep groove, unflanged, inner ring extended; type IV - deep groove, flanged, inner ring extended; type V - angular contact, unflanged, nonseparable, and counterbored outer ring; type VI - angular contact, flanged, nonseparable, and counterbored outer ring on flange side; type VII - angular contact, unflanged, separable, and stepped inner ring; type VIII - angular contact, flanged, separable, and stepped inner ring; type IX - angular contact, unflanged, nonseparable, and stepped inner ring. Materials inspection, passivation test, visual inspection, dimensional inspections, radial internal clearance, torque test, ball quality inspection, hardness test, surface roughness test, dimensional stability test, lubricant inspection, and calibration classification inspection shall be performed to meet the requirements prescribed.
SCOPE
1.1 This specification covers annular ball bearings intended primarily for use in instrument and precision rotating components. Instrument and precision ball bearings should meet tolerances specified in ABMA Standard 12.2, Instrument Ball Bearings Inch Design for Classes ABEC 5P and 7P.  
1.2 Intended Use—Ball bearings defined by this specification are intended for use in critical components of instrument systems. Such components range from air circulating blowers and drive motors through precision gear trains, gyro gimbals, and pickoffs to rate integrating spin-motors.  
1.3 The specification contains many of the requirements of MIL-B-81793, which was originally developed by the Department of Defense and maintained by the Naval Air Systems Command (Navy-AS) in Lakehurst, NJ. The following government activity codes may be found in the Department of Defense, Standardization Directory SD-1.2
