There is disclosed an apparatus for supporting roll chocks of a work roll in a roll stand housing. This apparatus includes a thrust transmitting head member between the roll chock and a rolling force effecting mechanism such as a screw of a screw down mechanism. The head member has a spherical surface at one end in contact with a mating spherical surface formed at one end of the screw. These spherical surfaces have different radii to make point contact therebetween and to enable rolling contact movement between the head member and the screw in the rocking motion of the roll chock caused by a force in a workpiece generated during a rolling operation, to thereby provide more accurate measurement of tension in the workpiece being rolled by employing force sensing devices acting on the roll chocks. The head member also has inclined surfaces at the other end thereof in registration with mating inclined surfaces formed at one side of the roll chock. The registration of these mating inclined surfaces make it possible to center the roll chock in the roll stand housing.
