Levelers

Reconditioning services for ALL manufactured brands of levelers.
Complete teardown, inspection, and reconditioning services. In addition, we can also upgrade your existing leveler.
Reconditioning services include, but are not limited to the following:

  • Work Rolls and Intermediate Rolls
    After demounting and inspection of the rolls, we will provide you a detailed inspection report including minimum diameter and hardness of the roll bodies. Once we have your order confirmation, we will proceed to the regrinding of the rolls to the same diameter with a tolerance of plus minus 0.005 mm.
  • Backup Bearing Rebuild
    We specialize in backup bearing rebuilds and bearing regrinding, which can provide significant cost savings over new. We have direct interchanges with all OEM manufacturers backup bearings, as well as other secondary manufacturers of backup bearing components for levelers.
    Once assembled, the products undergo a final control to check the complete conformity. Besides the dimension control, all the necessary verifications are made to guarantee the correct functioning of the product according to the requirements.
  • Backup Supports
    We can recondition your existing assemblies by replacing worn components to reduce side thrust and eliminate premature wear to back-up bearings.
  • Jacks
    We supply independent adjust jacks, top frame jacks and the internal components to recondition them.

Tension Levelers

Reconditioning services for ALL manufactured brands of tension levelers.
We can repair or refurbish your modules to their original factory specifications.
Reconditioning services include, but are not limited to the following:

  • Module Plates
    We indicate the module plate on a granite table to assure original design specifications. If needed, we will vertically stress relieve, and totally re-machine to original factory specifications. If we find that the bearing seats are in need of repair, we can apply a hardened weld overlay and then grind them back to original design specifications.
  • Work Rolls and Backup Roll Assemblies
    Work rolls and backup roll assemblies are reground and/or replaced, as needed. We engineer new replacement rolls and backups for virtually any manufacturer's module.
