Plain Bearing Test Methods
2024-04-18
WIP
ARP5448C
This SAE Aerospace Recommended Practice (ARP) establishes methods for testing airframe plain bearings. The purpose of ARP5448 and its associated slash sheets is to document test methods commonly used to evaluate airframe bearings. These test methods may be referenced in specifications, part standards, purchase orders, etc., when the test is deemed appropriate to the intended use of the bearing by the end user of the bearing. These test methods are not intended to encompass every conceivable requirement for an airframe bearing. The end user of the bearing must exercise engineering judgment to determine the most appropriate standard and/or nonstandard tests for the application.

Plain Spherical Bearing Conformity Examination
2023-03-13
WIP
ARP5448/6B
This method outlines a standard procedure for performing conformity tests of bearings utilizing liners of bonded polytetrafluoroethylene (PTFE). The data from these tests shall be used to determine if the product meets the conformity requirements of the applicable specification.
Standard

Plain Bearing Wear Measurement
2023-03-13
WIP
ARP5448/7B
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

Plain Bearing High Speed Oscillation Test
2022-09-27
WIP
ARP5448/2A
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.
Standard

Plain Bearing Low Speed Oscillation Test
2021-09-28
WIP
ARP5448/3B
This test method outlines a recommended procedure for performing unidirectional load dynamic testing of self-lubricating bearings at room temperature, elevated temperature or sub-zero temperature, dry or contaminated with fluids. The wear data from these tests is to be used for qualification and to establish bearing design criteria.
Standard

Rod End Locking Device Selection Criteria
2020-07-01
CURRENT
ARP6910
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.
Standard

Bearings, Sleeve, Plain and Flanged, Self-Lubricating
2019-09-16
CURRENT
AS81934C
This standard covers plain and flanged sleeve bearings which are self-lubricating by incorporating polytetrafluoroethylene (PTFE) in a liner in the bore for use in the temperature range of -65 to +325 °F.
