Model: H5471906-012D4

Special Features:

(1) at assembly thread bearing retainer pn 12 onto the ball screw nut pn 2 as close to flush as possible with end of ballnut thread. See section 11-58. Lubricate threads on the ballscrew nut pn 2 with aeroshell no 22 per dod-g-24508 (eb pn 52-06-37258). (2) position pn 12, locating (8) 0.406 diameter holes 22.5 degrees from 0.687 diameter hole in pn 31 and 0.500 keyways in pn 3. See section 10-2e.

Properties:

An item of any peripheral shape usually having one flat or spherical surface and a centrally located hole. It is designed for applications involving moving (kinetic) loads. Except for items fabricated from bearing quality synthetic (plastic) or composed of multilayer material, one bearing surface must either have a specific surface finish designation of 32 microinch (0.8 micrometre) or less, arithmetical average (aa) (arithmetic mean deviation) or one of the following conditions: be lapped or ground; have visible or detectable means of lubrication; grooves, indentations; or self-lubrication. The thickness must not exceed 25 percent of the outside diameter of the shortest distance between peripheral flats (when thickness and/or outside diameter is designated as a tolerance dimension, the maximum dimension will be used to determine compliance). Excludes straight, tubular (without flange) items having a bearing surface(s) parallel to the axis of the bore only. See also washer, flat and spacer, sleeve.
