This SAE Aerospace Standard (AS) covers airframe plain spherical bearings utilizing a copper-beryllium ball and corrosion resistant steel outer race for use between −65 °F and +350 °F.
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.
This standard defines general requirements for spherical, radial-journal, conical, and thrust bearings which are of laminated elastomeric construction. These bearings are for use in an environment having a temperature spectrum of -65 to +160 °F while reacting steady state loads in addition to oscillating loads and motions. The operating temperature range of -65 to +160 °F reflects the current temperature range for existing parts, but allows for expansion in the future.
This specification defines the requirements for fiber reinforced plastic (FRP) composition plain and flanged sleeve bearings that are self-lubricating and which are compatible with graphite-epoxy composites.

This standard details two methods of inspecting TFE lined spherical or journal bearing wear outside the test apparatus. The methods described herein are applicable only to bearings which were unidirectionally loaded and the area of sliding wear is known and held constant throughout the dynamic test. The two methods described are: a Destructive Inspection - Cut and measure (not applicable to molded liners) b Non-destructive Inspection - Radial play (gage) measurement
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.
