FAQ

Qu’est-ce qu’un roulement à rouleaux sphériques?

Les roulements à rouleaux sphériques ont une capacité de charge importante et peuvent s’auto-aligner. Ces roulements sont adaptés pour des applications à faible ou moyenne vitesse qui impliquent de fortes conditions de charge et des chocs. Les roulements à rouleaux sphériques sont constitués de deux rangées de rouleaux, ceci leur confère des propriétés d’auto-alignement. Ils peuvent supporter des efforts radiaux et axiaux. Les rouleaux ont des profils sphériques simples ou plus complexes. La piste de la bague extérieure est sphérique afin de compenser les erreurs de positionnement de l'arbre par rapport au logement et les défauts dus à la flexion de l’arbre. Les roulements à rouleaux sphériques sont les plus adaptés pour les applications nécessitant une grande capacité de charge ou une résistance aux chocs / impacts mais les vitesses acceptables sont plus réduites. Suivant les cas, ils peuvent être adaptés à des vitesses et des conditions de charges très importantes ou une lubrification dégradée.
