The data in the diagrams refer to 3-6 jaw chucks, newly maintained according to their service manuals using SMW-AUTOBLOK K67 grease. The static and dynamic gripping forces have been measured using standard soft top jaws, placed in a position not exceeding the outer diameter of the chuck. Soft and hard top jaws for IR-C Application/customer benefits • Chucking operations of very large components • Suitable for vertical machines thanks to the front protection of the slide ways IR-C: Manual radial setting of master jaws, TONGUE & GROOVE (type “American Standard”) (all diameters) Technical features • Gripping force transmission via wedge hook • Front protection of the slide ways against swarf and chips penetration • IR-C chucks with manual radial setting of master jaws for the workpiece centering Standard equipment Ordering example 3- or 6-jaw chuck 6-jaw chuck IR-C 1600 / Z720 1 set soft top jaws Mounting bolts Grease gun Technical data SMW-AUTOBLOK Type Number of jaws Radial jaw stroke (+ manual setting) mm Axial piston stroke mm Max. draw pull* kN Max. gripping force* kN Max. speed r.p.m. Weight (without top jaws) kg Moment of inertia kg·m2 Hard, reversible top jaw (piece) Id.
