Bearings, Sleeve, Plain and Flanged, Self-Lubricating
AS81934B
This standard covers plain and flanged sleeve bearings which are self-lubricating by incorporating polytetrafluoroethylene (PTFE) in a liner in the bore for use in the temperature range of -65 to +325 °F.
Rationale:
Updating this document to add an “A” part number designation, add LN2 exposure prior to dynamic tests, add low temp dynamic test, add separate qual for Al bushings, revise to Zn Ni Grade B, revise marking for -07 size and smaller, update packing note, add liner gap allowance, and revise de-icing note.
