Integrated COMBI Seals – Reliable Sealing for Muddy Dusty Field Conditions

A practical sealing solution for field equipment exposed to dirt, grit and wet mud. It helps block contaminant entry, protect rotating parts, and extend service intervals in demanding outdoor work.

Customer Pain Point

Field equipment often combines wet soil, grit and airborne dust. Once contamination reaches grease and bearings, wear accelerates and service intervals shrink.

Solution

The integrated COMBI layout adds external exclusion ahead of the primary lip to reduce contaminant tracking and support cleaner lubrication around rotating parts.

Applications

Field machinery, agriculture, construction and off-road equipment.
