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.
This standard defines the requirements for fiber reinforced plastic (FRP) composite plain and flanged sleeve bearings that are self-lubricating and which are compatible with graphite-epoxy composites.
This test method establishes a standard procedure for using plug gages to evaluate dimensional conformance of lined inside diameters of bearings. Bearings covered by this test method include sleeve bearings and lined bore spherical bearings. Note that this method gives no indication of true cylindricity.
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.
This SAE Aerospace Standard (AS) covers plain spherical bearings which are self-aligning and self-lubricating by utilizing polytetrafluoroethylene (PTFE) in a fabric composite or molded material that is bonded to the inner diameter surface of the race and when specified, to the bore diameter surface of the ball. These bearings are for use in the temperature range -65 to +325 °F (-54 to +163 °C).
