A rolling-element bearing 1 comprising an inner race 3, an outer race 2 and an array of rolling elements 4 arranged within a bearing cage 5 situated between the two races 2, 3, the inner surface of the bearing cage 5 being piloted on the inner race 3 for limiting eccentric movement of the cage 5 within the bearing 1 and further having a reservoir 9 formed between a pair of circumferential weirs 6a, 7b on the cage 5, the outer surface of the inner race 3 comprising a raised land portion 3d for contacting oil 9a in the reservoir 9 thereby to control the relative speed of the cage 5 and the inner race 3, wherein the radial depth of each weir 6b, 7b is greater than the maximum radial clearance between the land portion 3d and the cage 5 for maintaining said controlling contact between the land portion 3d and the oil 9a during said eccentric movement of the cage 5. |
