EN 2585-2001 pdf download.Aerospace series – Bearings, spherical plain in corrosion resisting steel with self-lubricating liner – Wide series – Elevated load at ambient temperature – Dimensions and loads.
This EN 2585 specifies the characteristics of spherical plain bearings in corrosion resisting steel, with self- lubricating liner, narrow series, for elevated load at ambient temperature, with or without swaging groove, intended for use in the fixed or moving parts of the aircraft structure and control mechanisms.
They shall be used in the temperature range — 550 C to + 163° C.

3 Symbols and definitions
The tolerance definitions are given in ISO 11 32• 1.
single plane mean bore diameter deviation
= deviation of a single bore diameter
= single plane mean outside diameter deviation
= deviation of a single outside diameter
a = angle of tilt of the outer ring with respect to the inner ring, the spherical surface of the outer ring being completely in contact with the inner ring
