Abstract

La présente invention concerne un rouleau équipé d'un palier à haute performance d'étanchéité et comprenant : un corps de cylindre (100), une partie de montage de siège de palier (110) étant formée au niveau de chacune de deux extrémités du corps de cylindre (100) ; des sièges de palier (200), respectivement montés dans les parties de montage de siège de palier (110) du corps de cylindre (100) ; des paliers (300), respectivement montés dans les sièges de palier (200), le palier (300) comprenant une bague intérieure de roulement (310), une bague extérieure de roulement (320), une cage (330) et une pluralité de billes (340) ; et un arbre de rouleau (400), monté dans une position centrale du corps de cylindre (100) par l'intermédiaire des paliers (300) et s'étendant axialement à travers le corps de cylindre (100). Le palier (300) comprend en outre un premier joint d'étanchéité (350) monté de façon amovible sur une surface d'extrémité externe de la bague intérieure de roulement (310), et le premier joint d'étanchéité (350) s'étend radialement et recouvre une surface d'extrémité externe de la bague extérieure de roulement (320). La surface d'extrémité externe du palier (300) du rouleau est rendue entièrement étanche par le premier joint d'étanchéité (350), ce qui évite les fuites de graisse et empêche l'humidité et la poussière d'entrer dans une surface de travail du palier, et garantit ainsi un fonctionnement normal du rouleau dans une plage de conditions de travail.
