Matrix Split Seal Saves Oil and Stops Leakage in Steel Mill Gearboxes

Challenge
Issue

  • A steel mill had significantly worn out shafts with the gearboxes on the “repeater” of the wire mill. The wear was caused by running various rubber-style lip seals.
  • Gearboxes were leaking oil consistently upon startup after a new competitor seal was installed. This progressively worsened causing significant oil/grease loss and major housekeeping issues.
AW Chesterton Matrix Rotary Seal will adjust to the shaft axis to avoid wear.
