Product Code:SAE AS81820
Title:Bearings, Plain, Self-Aligning, Self-Lubricating, Low Speed Oscillation
Issuing Committee:Acbg Plain Bearing Committee
Scope:This standard 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 掳F (-54 to +163 掳C).
