Product Code:SAE ARP5483
Title:Rolling Element Bearing Test Methods
Issuing Committee:Acbg Rolling Element Bearing Committee
Scope:This SAE Aerospace Recommended Practice establishes methods for testing airframe Rolling Element bearings. The purpose of ARP5483 and its associated slash sheets is to document test methods commonly used to evaluate airframe bearings. These test methods may be referenced in 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.
