A device for quickly replacing a work roll of a machine tool for the surface processing of plate- or strip-like work pieces. The work roll is journaled on suitable journal bearings and the machine tool is provided with roll carrier arms for attachment to the journal bearings. Each of the roll carrier arms comprises a coupling plate and each of the journal bearings comprises a corresponding coupling block for connection to the coupling plate. The coupling plate is provided with a pair of locking pins and the coupling block is provided with a pair of pinholes, for receiving the pair of locking pins when the coupling plate and the coupling block are in a coupling position. The coupling block is further provided with a pair of locking bolts rotatably mounted internally thereof and capable of being reversibly moved between first and second operative angular position
