A clamping system for securing hardmetal rolls includes a shaft having a groove, one or more clamping nuts having threads on the inner circumference which are mounted around the pressure ring having threads on the outer circumference by threading mechanism, pair of split clamps having wedge provided on the inner circumference of the split clamps and is accommodated in the groove provided on the shaft fixed to the pressure ring and acts as the bearing member of the mechanism to sustain the axial load applied by the screws. Plurality of screws passing through plurality of threaded holes provided on front face of the split clamps to prevent rotation of the hardmetal rolls. Plurality of locating pins are passed through the through holes provided at the mating face of the wedge of the split clamps to restrict radial movement of the split clamps and are used to fix the split clamps.
