Recherche rapide d’informations détaillées<br />

sur les produits<br />

Les numéros des tableaux des produits permettent<br />

d’accéder rapidement à des informations<br />

détaillées sur les produits. Ces numéros<br />

sont indiqués dans la table des matières au<br />

début du catalogue, dans celle au début de<br />

chaque chapitre sur les produits et dans l’index<br />

des produits à la fin du catalogue.<br />

Identification des produits<br />

Les désignations des roulements <strong>SKF</strong> contiennent<br />

en général des informations sur le roulement<br />

et des caractéristiques supplémentaires. Trois<br />

options sont disponibles pour spécifier un roulement<br />

<strong>SKF</strong> et trouver plus d’informations le<br />

concernant :<br />

• Index des produits<br />

L’index des produits en fin de catalogue<br />

répertorie les désignations des séries, indique<br />

les types de roulements s’y rapportant et guide<br />

le lecteur vers le chapitre et le tableau des<br />

produits correspondants.<br />

• Systèmes de désignation<br />

Dans chaque chapitre sur les produits, les<br />

désignations des produits sont situées dans<br />

les pages précédant les tableaux des produits.<br />

Ces systèmes identifient les préfixes et suffixes<br />

de désignation les plus courants.<br />

• Index de texte<br />

L’index de texte à la fin du catalogue contient<br />

les suffixes de désignation par ordre alphabétique.<br />

Ils sont imprimés en gras pour faciliter<br />

la lecture.<br />
