La présente Norme internationale spécifie les dimensions d'encombrement et les tolérances de la classe normale des roulements à aiguilles des séries de dimensions 48, 49 et 69, telles que données dans l'ISO 15. Ces séries sont prévues pour des roulements à aiguilles complets et pour des roulements sans bague intérieure. La présente Norme internationale n'est pas applicable aux douilles à aiguilles.
Le présent document complète la norme NF ISO 1206 par l'ajout d'une annexe informative définissant les tolérances du chemin de roulement de l'arbre (écart du diamètre, rugosité de surface, circularité et variation du diamètre extérieur moyen) pour les roulements à aiguilles sans bague intérieure.
This document specifies the boundary dimensions and normal class tolerance values for needle roller bearings with machined rings. This document specifies dimensional and geometrical characteristics, and limit deviations from nominal sizes. These specifications apply to complete needle roller bearings and to bearings without inner ring.
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!
