ABSTRACT:
A screwdown is replaceably inserted in the window of a rolling mill housing between a bearing chock and a surface defining the window of the housing. The screwdown which is provided for each of the pair of rolling mill housings includes a screwdown housing carrying a nut member which receives a screw which is locked against rotation by a lock plate supported by the screwdown housing. Gear teeth are formed on the outer cylindrical surface of the nut and these teeth mesh with the teeth of a worm gear on a shaft which is supported by the screwdown housing for rotation. The shaft of one screwdown housing is coupled to a torque shaft which extends through and supported by the other screwdown housing. The shafts are releasably locked together for synchronous or independent rotation.
