Scope:

This standard covers the requirements for spherical, self-aligning, self-lubricating bearings which are for use in the ambient temperature range -65 to +160 °F (-54 to +71 °C) at high cyclic speeds. The scope of the 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.

Rationale:

The reason for updating this document is to bring qualification testing in line with current industry test capabilities. This procurement document deletes the class of products for sleeve and thrust bearings as well as the bearing dash numbers of -1, -3, and -4, only the -2 remains. Other sizes with liner thickness less than 0.015” will be offered in a new standard.

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.
