Aerospace series - Bearing spherical plain, metal to metal, in corrosion resisting steel, cadmium plated - Wide series - Dimensions and loads - Inch series

This European Standard specifies the characteristics of spherical plain bearings, metal to metal, in corrosion resisting steel, cadmium plated and chromated, wide series, inch series for aerospace applications.
They are intended for use in fixed or moving parts of the aircraft structure and their control mechanisms.
They need to 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-23827C, operating temperature range  73 °C to 121 °C;
-   Code B: Grease as per MIL-PRF-81322G, 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 needs to be provided with a dry-film lubricant as per MIL-PRF-46010G or equivalent (anti-seizing protection).
The slide hole treatment either at the outer ring or inner ring.

Luft- und Raumfahrt - Gelenklager, Metall auf Metall, aus korrosionsbeständigem Stahl, verkadmet - Breite Reihe - Maße und Belastungen - Inch Reihe

Die vorliegende Norm legt die Eigenschaftsmerkmale von verkadmeten und chromatierten Gelenklagern Metall auf Metall aus korrosionsbeständigem Stahl, breite Reihe, Inch-Reihe (Zoll-Reihe) für Anwendungen in der Luft  und Raumfahrt fest.
Sie sind für den Einsatz an starren oder beweglichen Flugwerkteilen und deren Betätigungsmechanismen bestimmt.
Sie sind für Betriebstemperaturen im Bereich von –54 °C bis 150 °C zu verwenden, wenn sie mit folgenden Schmierfetten gefettet werden:
Kennbuchstabe A:   Schmierfett nach MIL-PRF-23827C, Betriebstemperaturbereich von –73 °C bis 121 °C.
Kennbuchstabe B:   Schmierfett nach MIL-PRF-81322G, Betriebstemperaturbereich von –54 °C bis 177 °C.
Der Einsatzbereich von Wälzlagern, die mit Schmierfett nach Kennbuchstabe A gefettet sind, ist auf 121 °C begrenzt.
In beiden Fällen ist die sphärische Laufbahn des Außen  oder Innenrings mit einem Trockenschmierstoff nach MIL PRF 46010G oder einem gleichwertigen Schmierstoff (einer schmierenden Beschichtung — Anti-Seize-Paste) zu versehen.
Die Gleitbahnbehandlung erfolgt entweder auf dem Außen- oder Innenring.

Série aérospatiale - Rotules lisses métal à métal en acier à la corrosion, cadmiées - Série large - Dimensions et charges - Séries en inches

La présente Norme européenne spécifie les caractéristiques des rotules lisses, métal à métal, en acier
résistant à la corrosion, cadmiées et chromatées, séries larges, séries en inches pour applications
aérospatiales.
Elles sont conçues pour être utilisées dans les parties fixes ou mobiles de la structure des aéronefs ou dans
les mécanismes de commande.
Elles doivent être utilisées dans une plage de températures de  54 °C à 150 °C. Elles sont lubrifiées au
moyen des graisses suivantes :
 Code A : Graisse suivant la MIL-PRF-23827C, plage de température d'utilisation de  73 °C à 121 °C ;
 Code B : Graisse suivant la MIL-PRF-81322G, plage de température d'utilisation de  54 °C à 177 °C.
La gamme d'application pour des rotules lubrifiées avec la graisse code A est limitée à 121 °C.
Dans les deux cas, la surface sphérique de la bague extérieure ou intérieure doit être protégée avec un film
lubrifiant sec selon la MIL-PRF-46010G ou un équivalent (protection anti-grippage).
Le trou de coulisse est traité soit sur la bague extérieure ou la bague intérieure.
