Edition date: 2026-10-07
In Force
Available languages: English, French
Summary: This document 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 are used in the temperature range as determined by the grease capability as below: - code A: greased as per MIL-PRF-23827 Type I, operating temperature range −73 °C to 121 °C; - code B: greased 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 are 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.

Le présent document 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 de l’aéronef et leurs mécanismes de commande. 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.
