Abstract: The invention relates to a steady rest (1) for supporting an elongated workpiece (2), comprising a middle arm (4) moveable in its axial direction by a power means and two pivotally movable outer arms (5, 6). An arrangement provides a separate driving connection for the outer arms (5, 6) with the middle arm (4) by acting on a lever (5c, 6c) of each outer arm for pivoting the outer arms towards the workpiece. The arrangement comprises for each driving connection two rollers (9a, 9b, 10a, 10b) arranged on a lateral extension (11a, 11b) of the middle arm (4) and configured to roll on a respective cam (12a, 12b, 13a, 13b) arranged on the lever (5c, 6c) of the respective outer arm. The invention also relates to a machining tool provided with such a steady rest and use of such a steady rest.
