A bearing arrangement 2 comprising an outer race 10, a shaft 4 arranged to rotate with respect to the outer race 10 thereby defining an axis of rotation 8 of the shaft 4. The shaft 4 and the outer race 10 are arranged to define a region of overlap between the shaft 4 and the outer race 10 along the axis of rotation. An inner race 12 is disposed between the outer race 10 and the shaft 4 in the region of overlap and coupled for rotation with the shaft 4, the inner race 12 and the shaft 4 defining an annular reservoir 40 between them for accommodating radial expansion of the shaft 4 or radial displacement of the shaft 4 with respect to the axis of rotation 8. |
