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.
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.
ISO 1206:2018 specifies the boundary dimensions and normal class tolerance values for needle roller bearings with machined rings. ISO 1206:2018 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. Recommended values for the tolerances for shaft raceways for needle roller bearings without inner ring are given in Annex A.
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.
