Aerospace series - Bearing, spherical, plain, in corrosion resisting steel - Narrow series - Dimensions and loads - Inch series

This European standard specifies the characteristics of inch based spherical plain bearing, 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 as determined by the grease capability as below:
— code A: grease as per MIL-PRF-23827 Type I, operating temperature range −73 °C to 121 °C;
— code B: grease as per MIL-PRF-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).

Luft- und Raumfahrt - Gelenklager aus korrosionsbeständigem Stahl - Schmale Reihe - Maße und Belastungen - Inch-Reihe

Diese Europäische Norm legt die Eigenschaften von Gelenklagern, Metall auf Metall, schmale Reihe, Inch Reihe, fest.
Sie sind für die Verwendung in starren oder beweglichen Flugwerkteilen und deren Betätigungs-mechanismen bestimmt.
Sie müssen im von der Schmierfähigkeit bestimmten Temperaturbereich wie nachfolgend beschrieben verwendet werden:
   Kennbuchstabe A: Schmierstoff nach MIL PRF 23827 Typ I, Betriebstemperaturbereich −73 °C bis 121 °C;
   Kennbuchstabe B: Schmierstoff nach MIL PRF 81322, Betriebstemperaturbereich −54 °C bis 177 °C.
Der Anwendungsbereich für Lager, die mit Schmierstoffen nach Kennbuchstabe A geschmiert sind, ist auf 121 °C begrenzt.
In beiden Fällen muss auf die Kugelfläche des Außenrings oder Innenrings ein Trockenschmierstoff nach MIL PRF 46010 oder Ähnliches aufgebracht werden (Schutz gegen Festfressen).

Série aérospatiale - Rotule lisse en acier résistant à la corrosion - Série étroite - Dimensions et charges - Série en inches

La présente norme européenne spécifie les caractéristiques des rotules lisses en inches, métal sur métal, en acier résistant à la corrosion, série étroite.
Elles sont destinées à être utilisées pour les parties fixes ou mobiles de la structure des aéronefs et leurs mécanismes de contrôle.
Elles doivent être utilisées dans la plage de températures déterminée en fonction des capacités de la graisse suivantes :
-   code A : graisse conforme au Type I de la MIL PRF 23827, plage de températures de fonctionnement de −73 °C à 121 °C ;
-   code B : graisse conforme à la MIL PRF 81322, plage de températures de fonctionnement de −54 °C à 177 °C.
La plage d’application des rotules lubrifiées à l’aide de graisse suivant le code A est limitée à 121 °C.
Dans les deux cas, la surface sphérique de la bague extérieure ou intérieure doit être pourvue d’un lubrifiant à film sec selon la MIL PRF 46010 ou équivalente (protection anti grippage).
Le traitement des trous de coulissement se situe au niveau de la bague extérieure ou de la bague intérieure.
