Mechanics of Cold Rolling of Thin Strip 443 where yiw is the vertical deflection of the work roll at element i, gijw (, ) is the influence function for the work roll deflection due to the combined bending and shear forces generated by rolling load, giwf is the influence function for the work roll deflection due to the force generated by the roll bending mechanism, k represents the minimum element

The work rolls in four-high strip mills and the rolls in two-high light-section and wire rod mills are mostly fitted with angular contact ball bearings as axial bearings. The chock arranged on the drive end is not axially located in the roll stand, but is guided on the roll neck by the axial bearing.

the heaviest rolls. The largest roll grinder in the world, made by Herkules, machines rolls up to 300 t; a machine of the type WS 1100 recently ground a plate mill roll with a weight of 230 t in chocks with combined hydrostatic-hydrodynamic bearings – that is a world record.
