Caract\u00e9ristiques cl\u00e9s<\/h3>\n
    \n
  • Supporte des charges radiales et axiales combin\u00e9es<\/li>\n
  • Haute capacit\u00e9 de charge<\/li>\n
  • Performance stable en fonctionnement continu<\/li>\n
  • Frottement et g\u00e9n\u00e9ration de chaleur r\u00e9duits<\/li>\n
  • Longue dur\u00e9e de vie dans des environnements lourds<\/li>\n
  • Adapt\u00e9 aux conditions de choc et de vibration<\/li>\n<\/ul>\n

    Applications<\/h3>\n
      \n
    • Moyeux de roues automobiles<\/li>\n
    • Bo\u00eetes de vitesses et syst\u00e8mes de transmission<\/li>\n
    • Machines agricoles<\/li>\n
    • Les machines de construction<\/li>\n
    • Syst\u00e8mes d'entra\u00eenement industriels<\/li>\n
    • \u00c9quipements miniers et lourds<\/li>\n
    • Syst\u00e8mes de convoyage et de manutention de mat\u00e9riaux<\/li>\n<\/ul>\n

      Avantages techniques<\/h3>\n

      La structure du roulement conique am\u00e9liore l'efficacit\u00e9 de contact entre les rouleaux et les chemins de roulement, permettant au roulement de supporter des charges plus \u00e9lev\u00e9es par rapport aux roulements \u00e0 billes standard.<\/p>\n

      Cela r\u00e9duit \u00e9galement la concentration de stress, am\u00e9liore la stabilit\u00e9 d'alignement et renforce la r\u00e9sistance \u00e0 la fatigue lors d'une utilisation \u00e0 long terme.<\/p>\n

      Options personnalis\u00e9es<\/h3>\n
        \n
      • Ajustement du jeu interne<\/li>\n
      • S\u00e9lection du mat\u00e9riau de la cage (acier ou laiton)<\/li>\n
      • Options de design scell\u00e9 ou ouvert<\/li>\n
      • Remplissage de graisse haute temp\u00e9rature<\/li>\n
      • Support de marque et d'emballage OEM<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"
