CURRENT
ARP5448/4
This test method outlines a recommended procedure for performing bond integrity tests of bonded peelable woven fabric reinforced polytetrafluoroethylene (PTFE) liners, hereafter referred to within this document as "PTFE liner" or "liner". The data from these tests shall be used to determine if the product meets the "bond integrity" requirements of the applicable specifications.

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).

AS82819
This standard covers the requirements for spherical, self-aligning, self-lubricating, bearings which are for use in the ambient temperature range of -65 to +160 °F (-54 to +71 °C) at high cyclic speeds 300 cpm (13 fpm) for liners with a thickness less than 0.015 inch. The scope of this standard is to provide a liner system qualification procedure for helicopter sliding bearings defined and controlled by source control drawings. Once a liner system is qualified, the source-controlled bearings are further tested under application conditions. Under Department of Defense (DoD) Policies and Procedures, any qualification requirements and associated Qualified Products List (QPLs) are mandatory for DoD contracts. Any materials relating to QPLs have not been adopted by SAE and are not part of this SAE technical document.
