A bearing isolator assembly for sealing a rotating shaft with a porous sealing element including a rotor configured to sealingly engage with a shaft, and a stator configured to sealingly engage with a housing of an assembly. The rotor and stator are configured to engage with each other to define a labyrinthine pathway and one or more cavities, in which may be disposed a unitizing element and a porous sealing element. The porous sealing element provides a barrier to particulate contaminants from entering the interior of the housing, and to prevent egress of lubricants from the interior of the housing. The unitizing element limits axial and/or radial movement of the rotor with respect to the stator, and helps prevent wear of the rotor and/or stator by helping prevent the rotor from contacting the stator during operation.
Ensemble isolant pour palier utilisable avec un arbre rotatif, comportant un joint poreux qui comprend un rotor s'enclenchant hermétique avec un arbre, et un stator qui s'enclenche hermétique avec une enceinte entourant un ensemble. Le rotor et le stator s'enclenchent pour définir un labyrinthe et une ou plusieurs cavités, permettant d'accueillir un élément de liaison et un joint poreux, lequel assure une barrière vis-à-vis des contaminants particulaires pour les empêcher de pénétrer dans l'enceinte, et empêche la sortie de lubrifiants depuis l'intérieur de l'enceinte. L'élément de liaison limite le mouvement axial et/ou radial du rotor par rapport au stator, et contribue à éloigner l'usure du rotor et/ou du stator en contribuer à éviter les contacts rotor/stator durant le fonctionnement.
