Trans-Pacific Aerospace spherical bearings and aerospace products have successfully met the verification test qualification requirements set by the AS81820 Aerospace Standard. 

SAE-AS 81820

This SAE Aerospace Standard (AS) covers self-aligning and self-lubricating plain spherical bearings that utilize polytetrafluorothylene (PTFE) in a molded material or fabric composite that is bonded to inner diameter surface of the race and, when specified, to the bore diameter surface of the ball. These bearings can be used in the temperature range -65 to +325°F (-54 to +163°C).
