ABSTRACT OF THE DISCLOSURE: A motorized rest for supporting a piece being worked by grinding machines for cylinders, rollers and the like, comprises a fixed lower body suitable for being joined to a bench of the grinding machine, on which an upper body is slidingly arranged so as to be movable transverse to the axis of rotation of the piece, provided with two or more sliding blocks for support of the piece itself in an area not subjected to working and connected to the fixed lower body by means of a connecting rod having an axis parallel to the envisaged relative direction of sliding of the bodies of the rest. The connecting rod is joined to the fixed body by means of a support pin consisting of an eccentric shaft which can be operated in rotation by a servomotor provided with a speed reduction gear with high reduction ratio. There are also flexible means interposed between lower body and upper body for compensation of the play in each case, lubricating devices for the respective sliding surfaces of the lower body and of the upper body and controllable clamping means gripping between them by friction the respective sliding surfaces of the lower body and of the upper body.
