A bearing lining has a bearing backing layer provided with a coating comprising a first overlay layer and a second overlay layer, the first overlay layer being provided between the bearing backing layer and the second overlay layer. The first and second overlay layers each comprise a matrix material and a soft-phase material that is substantially insoluble in the matrix and dispersed within the matrix as soft-phase particles. The first overlay layer comprises a higher proportion by weight of a grain size reduction additive than the second overlay layer. |
