1. A journal bearing comprising a first component and a second component, the first component and the second component being arranged to rotate relative to one another in normal use, wherein the first component comprises:
a first body that has an axis defining an axial direction and a radial direction perpendicular to the axial direction;
a first layer forming a functional surface facing the second component; and
a first subsurface layer between the first body and the first layer;
wherein the first subsurface layer is formed of a material having a first coefficient of thermal expansion in the radial direction, and the first body is formed of a material having a second coefficient of thermal expansion in the radial direction;
wherein the first coefficient of thermal expansion is lower than the second coefficient of thermal expansion;
wherein the first subsurface layer comprises a fibre-reinforced plastic; and
wherein the fibres in the fibre-reinforced plastic are predominantly oriented in the radial and circumferential directions.
