MIL-B-1083.pdf

This is a Military Standard (MS19060) specification document for corrosion resistant steel bearing balls. The standard establishes requirements for the design, manufacturing, testing, and quality assurance of bearing balls made from corrosion resistant steel conforming to UNS S44003 or UNS S44004 chemical compositions per ASTM A276 specifications.

The document provides comprehensive technical requirements including material hardness specifications of 58-65 HRC equivalent, surface roughness tolerances by grade (ranging from 0.5 to 8.0 microinches for grades 3 through 200), and allowable variations in ball diameter and spherical form by grade. The standard defines dash numbers and corresponding dimensions across multiple grades (3, 5, 10, 16, 48, 100, and 200), with ball diameter nominal sizes ranging from 1/64 inch to 2-1/2 inches. Material density is specified at 277 pounds per cubic inch. Part numbering consists of the basic MS number followed by a dash number from the provided tables. The document includes tolerance tables for individual ball diameter variations, deviation from spherical form, surface roughness limits, lot diameter variations, ball gage deviations, and container marking increments. Additionally, it provides dash number changes and superseded part number replacements for previous versions (MS9461 series). This is an entire standard revised document applicable to procurement specifications and procurement specification MIL-B-1083 with supersedes MS 9461.
