NPFC - MIL-B-8942
BEARINGS, PLAIN, TFE LINED, SELF-ALIGNING
|Publication Date:||15 November 1965|
This specification covers plain spherical bearings which are self-aligning and self-lubricating by incorporating tetrafluoroethylene (TFE) in a liner between the inner ring (ball) and outer ring (race) for use in the temperature range −65° F to +250° F.
The bearings are intended primarily for use in applications where moderate friction and bearing play at low rotational oscillatory speeds are not objectionable.
