The calender is a machine tool featuring two or more cylindrical rollers. Thanks to their inherent self-locking mechanism and the ability to perfectly maintain positioning even under significant loads, Unimec Screw Jacks are the ideal solution to correctly position the adjustable rollers in a calender system. Additional accessories, such as our Rod-End Bearing End-Fittings and Clevis-Style Rigid Protections are also an integral part of a calender solution allowing a smooth and consistent adjustment of the rollers

Unimec makes the world's largest and heaviest Screw Jacks ever manufactured. These units were specifically created for Carlo Carnaghi, a world leader in vertical lathes and large size milling machines. These special Screw Jacks feature 8,000 mm (26.6 ft.) long, dia 160 mm x lead 28 mm spindles creating a colossal 60 ft. x 40 ft. machine. Despite the enormous size of the machine and the considerable distance between the spindles, our system guarantees an extremely accurate positioning with a maximum lead discrepancy of only 0.06 mm (less than 0.0025")
