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 ARP discusses common rod end locking devices with recommended applications and some of the advantages and disadvantages of specific configurations. An appendix is included with factors to be considered for selection of positive locking devices and a discussion of safetying devices for rod end assemblies.

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 1400 cpm (15 fpm). 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.

This test method outlines a standard procedure for performing cyclic reversing load testing on oscillating sliding bearings. The wear data from these tests is to be used for qualification requirements and to establish bearing design criteria.

This standard details two methods of inspecting PTFE 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. Nondestructive Inspection - Radial play (gauge) measurement
