Special Features:

Each bearing to be identified by serial no. On outer ring; balls to be visually insp w/10 power magnification prior to final assembly; eddy current insp balls for cracks using a probe, no cracks are acceptable; fluorescent penetrant insp per hs447, gr v ref mil-i-6866 magnetic particle insp per hs31, cl iii ref mil-i-6868 except wet residual method may be used; surface temper insp both rings per hs972 ref mil-std-8671, surfaces shall not exhibit any evidence of surface temper; actual specific gravity value of the retainer shall be recorded for each bearing serial no

Properties:

A cylindrical device in which the inner or outer ring turns upon a single or double row of hardened balls which roll easily between the two rings, thus minimizing friction. For items with faces specially ground for duplex mounting see bearing, ball, duplex. Excludes bearing, ball, airframe.
