We offer complete range of Sendzimir work, intermediate, driving  and back-up rolls, for cluster cold rolling mills, such as  6Hi, 12Hi and 20-Hi. These rolls are hardened across its full diameter to the hardness, which corresponds to roll type and purpose.
 
Our trough hardened rolls are produced in following dimensional range:

  • from 20 up to 350 mm diameter
  • up to 3000mm length
  • up to 2500 kg  weight
  • up to 67 HRC hardness
