Title
Bearings, Plain, Self-Aligning, Self-Lubricating, Low Speed Oscillation
Scope
This SAE Aerospace Standard (AS) covers plain spherical bearings which are self-aligning and self-lubricating by utilizing polytetrafluoroethylene (PTFE) in a fabric composite or molded material that is bonded to the inner diameter surface of the race and when specified, to the bore diameter surface of the ball. These bearings are for use in the temperature range -65 to +325 °F (-54 to +163 °C).
Rationale
It was brought to the committee's atttention that the document has been published with a requirement that needs further clarification. Without this clarification it is possible for a manufacturer to do much more testing then is required.
