Abstract

L'invention concerne un palier lubrifié par un fluide, en particulier un palier à roulement ou un palier lisse, comprenant deux bagues de palier (1, 2) et un chemin de roulement (3, 4) agencé respectivement sur chaque bague de palier (1, 2), et une anode sacrificielle (6) qui est associée à au moins une (1) des deux bagues de palier. L'invention vise à proposer un palier lubrifié par un fluide à anode sacrificielle dont le comportement opérationnel soit moins influencé par l'anode sacrificielle. A cet effet, l'anode sacrificielle (6) est agencée à l'extérieur de l'intérieur (7) des bagues formé entre les bagues (1, 2) et l'anode sacrificielle (6) est reliée à l'intérieur (7) des bagues de manière électroconductrice.
