This method outlines the standard procedure for testing the hardness of bearing components. Bearings covered by this test method shall be any rolling element bearing used in airframe control.
This SAE Aerospace Standard (AS) covers sealed, self-aligning, anti-friction, rod end ball bearings with application in temperature ranges (1) -65 to 250 °F and (2) -65 to 300 °F with 20% reduction of dynamic load carrying capacity when subjected to operation above 250 °F.
