Le 22312 Roulement \u00e0 rouleaux sph\u00e9riques<\/strong> est un roulement robuste \u00e0 double rang\u00e9e con\u00e7u pour supporter des charges radiales extr\u00eamement \u00e9lev\u00e9es et des charges axiales mod\u00e9r\u00e9es tout en compensant le d\u00e9salignement de l'arbre. Son design de chemin de roulement sph\u00e9rique permet un alignement automatique, garantissant des performances stables m\u00eame en cas de d\u00e9viation de l'arbre ou d'erreurs d'installation.<\/p>\n

Compar\u00e9 \u00e0 la s\u00e9rie 22200, les roulements de la s\u00e9rie 22300 offrent une capacit\u00e9 de charge plus \u00e9lev\u00e9e, une durabilit\u00e9 accrue et une meilleure r\u00e9sistance aux chocs et aux vibrations<\/strong>, ce qui les rend id\u00e9aux pour des environnements industriels exigeants tels que l'exploitation mini\u00e8re, la production d'acier et les machines lourdes.<\/p>\n

Fabriqu\u00e9 en acier alli\u00e9 ou en acier au chrome de haute qualit\u00e9, le roulement 22312 offre une excellente r\u00e9sistance, une r\u00e9sistance \u00e0 l'usure et une longue dur\u00e9e de vie dans des conditions de charge lourde continues.<\/p>\n
