WIP Standard
AS4726A
This specification establishes the requirements for self-locking nuts, wrenching type (i.e., hexagon, double hexagon, and spline drive), made of a corrosion and heat resistant steel of the type identified under the Unified Numbering System as UNS S66286. Classification: a. 220 ksi minimum tensile strength at room temperature and b. 850 degrees F maximum test temperature of parts. Primarily for use in aerospace propulsion systems in temperatures up to approximately 850 degrees were nuts are used with bolts capable of developing 220 ksi axial tensile strength at room temperature, and having UNJ thread form.

ARP1202B
This Aerospace Recommenced Practice (ARP) defines a series of ball bearings which are specifically designed to support the rotor in a dynamic balancing machine. By establishing certain bearing sizes the number of required balancing machine support adapters will be reduced. The intent is that each size bearing identified by its outside diameter and width will be capable of accommodating any bore diameter within the specified range of that size. This ARP specifies both the nominal dimensions and the tolerances for a series of ball bearings with semifinished inside diameters which are suitable for supporting gas turbine rotating components in dynamic balancing machines.
