EN 2022-1988 pdf download.Aerospace series Bearings, spherical plain in corrosion resisting steel with self lubricating liner Light series Dimensions and loads.
This EN 2022 specifies the characteristics of spherical plain bearings in corrosion resisting steel with self
lubricating liner, light series.
They are intended for use in fixed or moving parts of the aircraft structure and control mechanisms.
They shall be used in the temperature range — 55 to + 150

3 Symbols
d. = the deviation of a single bore diameter
= the deviation of a single outside diameter mp = single plane mean bore diameter deviation flmp = single plane mean outside diameter deviation
a = maximum displacement angle which can be formed by the outer ring with the inner ring the spherical track of the outer ring being fully in contact with the inner ring.
4 Required characteristics
4.1 Dimensions — Tolerances — Masses
Configuration shall correspond with Figure 1 or Figure 2.
Dimensions, tolerances and masses shall correspond with Table 1.
4.2 Loads — Starting torques
Loads and starting torques shall correspond with Table 2.
4.3 Materials
Where the following code for tyw is applied:
R = with swaging grooves
S = without swaging groove
NOTE If necessary, the originator code S9005 may be introduced between the description block and the identity block.
6 Marking
In addition to the manufacturer’s own marking, each spherical plain bearing shall be marked, using the identity block as defined in clause 5 of this standard.
Marking position and method are at the manufacturer’s option.
7 Technical specification
Bearings, spherical plain supplied to this standard shall conform with the requirements of EN 2064.EN 2022-1988 pdf download.
