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.
