摘要： A gas bearing assembly for a gas bearing spindle. The assembly comprises a housing portion (11) and an inner radial bearing portion (10) disposed within and resiliently mounted relative to the housing portion. The inner radial bearing portion comprises an inner shell bearing portion (12) having a bearing face, and an intermediate sleeve portion (14) which is disposed between the inner shell bearing portion and the housing portion. A liquid coolant channel (7) is provided between the inner bearing shell portion (12) and the intermediate sleeve portion (14). The assembly further comprises an anti-rotation plug (601, 901) which is received in both the housing portion (11) and the inner bearing portion (10) to couple the housing portion and the inner bearing portion against relative rotation.
