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.

Chesterton Matrix Rotary Seal will adjust to the shaft axis to avoid wear.

Solution
Overview
Replaced competitor’s seal with the Chesterton Matrix Rotary Seal, a split polymer seal that can be installed in minutes minimized critical downtime.

• A unitized design.
• Advanced polymer combined with impregnated synthetic fiber packing technology to maximize performance.
• Positively seals out bearing contamination while keeping lubrication in.
• Withstands large runout conditions and vibration.

Leak-free performance saved over 177K in oil in six months
