Abstract
The invention relates to a lighter bearing assembly, in which the bearing includes an outer sleeve and an inner sleeve that rotate in relation to each other, the outer sleeve being set in a bearing block and the inner sleeve being set on a shaft, and one of the sleeves being arranged for axial movement relative to its support surface, and a pocket being arranged in the movement surface thus formed, to which a lubrication channel extends, to facilitate axial movement, such as that due to thermal expansion, the pocket being formed by a sealed area that delimits part of the movement surface.
