Le 6308 Roulement \u00e0 billes \u00e0 gorge profonde<\/strong> est un roulement robuste con\u00e7u pour supporter des charges radiales \u00e9lev\u00e9es et des charges axiales mod\u00e9r\u00e9es dans les deux directions. Avec des rainures de piste profondes et des billes en acier de pr\u00e9cision, il garantit une rotation fluide, un faible frottement et des performances fiables dans des conditions de fonctionnement exigeantes.<\/p>\n

Fabriqu\u00e9 en acier au chrome de haute qualit\u00e9, et disponible en variantes en acier inoxydable et en c\u00e9ramique, le roulement 6308 offre une excellente durabilit\u00e9, une r\u00e9sistance \u00e0 l'usure et une protection contre la corrosion. Il est propos\u00e9 dans plusieurs configurations, y compris type ouvert, protection m\u00e9tallique (ZZ) et \u00e9tanch\u00e9it\u00e9 en caoutchouc (2RS), ce qui lui permet de fonctionner efficacement dans divers environnements industriels.<\/p>\n

Gr\u00e2ce \u00e0 sa construction robuste et \u00e0 sa haute capacit\u00e9 de charge, le roulement 6308 est largement utilis\u00e9 dans les machines lourdes, les moteurs \u00e9lectriques, les \u00e9quipements miniers et les syst\u00e8mes de transmission industriels.<\/p>\n
