NF EN 4854-2

Aerospace series - Bearing, spherical plain, in corrosion resisting steel with self-lubricating liner, low starting torque and low friction coefficient, elevated duty cycles under low oscillations at different operating conditions, wide series - Part 2 : dimensions and loads

Le présent document spécifie les caractéristiques des rotules lisses résistant à la corrosion, à garniture autolubrifiante, faible couple de démarrage et faible coefficient de frottement, cycles d'endurance élevés sous faibles oscillations à différentes conditions de fonctionnement, série large pour applications aérospatiales. Ces rotules lisses autolubrifiantes sont destinées à être utilisées dans les parties fixes ou mobiles de la structure de l'aéronef, particulièrement pour les mécanismes de commande et les systèmes d'exploitation. Les rotules sont conçues pour être soumises à de faibles charges radiales dynamiques et à des rotations lentes dans une plage de température de -55 à 120 °C (-67 à 248 °F) .

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!

- The UPSELL service allows you to easily update one of your standards.
- With a single click, add a new language, the Requirements or Redline+ service and add one or more additional users.
