scope:
This European standard specifies the characteristics of inch based spherical plain bearings, metal to metal, in corrosion resisting steel, narrow series.
They are intended for use in fixed or moving parts of the aircraft structure and their control mechanisms.
They shall be used in the temperature range −54 °C to 150 °C. As they are lubricated by means of the following greases:
- code A: grease as per MIL-PRF-23827, operating temperature range −73 °C to 121 °C;
- code B: grease as per MIL-G-81322, operating temperature range −54 °C to 177 °C.
The range of application for bearings lubricated with grease per code A is limited to 121 °C.
In both cases the spherical surface of the outer or inner ring have to be provided with a dry-film lubricant as per MIL-PRF-46010 or equivalent (anti-seizing protection).
The slide hole treatment either at the outer ring or inner ring.
