Sticky mud and grease hold abrasive particles in place around rotating components. That constant contact increases the chance of contamination entering the sealing zone.
An integrated COMBI seal adds an external exclusion barrier before the main oil lip, helping separate the dirty environment from the lubricant side.
Helps exclude mud, grime and grit
Reduces abrasive exposure at the shaft track
Supports cleaner lubrication
Helps prevent contamination-driven leakage
Suitable for heavy construction machinery
Where packed dirt remains around hubs and shafts, layered exclusion directly targets the source of repeated seal damage.
