Product Code:SAE AS7452
Title:Bolts and Screws, Steel, Low Alloy Heat Treated, Roll Threaded
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope:This procurement specification covers aircraft quality bolts and screws made from a low alloy steel of the type identified under the Unified Numbering System as UNS G87400, and of a series of room temperature tensile strengths ranging from 125 000 to 185 000 psi.Product Code:SAE AS81819
Title:Bearings, Plain Self-Aligning, Self- Lubricating, High Speed-Oscillation -65 to +160 °F, General Specification For
Issuing Committee:Acbg Plain Bearing Committee
Scope:This standard covers the requirements for spherical, self-aligning, self-lubricating bearings which are for use in the ambient temperature range -65 to +160 °F (-54 to +71 °C) at high cyclic speeds. The scope of the 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.
