Integrated COMBI Seals – Mud Ingress Control for Dusty Rotary Systems

When mud tracks past the seal, grease contamination and bearing wear follow. Integrated COMBI seals add exclusion features that help interrupt contaminant paths before they reach the main sealing area.

Customer Pain

Mud tracking past an exposed lip carries grit into grease, and the resulting contamination quickly attacks bearings and shaft surfaces.

Solution

The integrated COMBI layout adds exclusion stages that help break the contaminant path before mud reaches the primary sealing zone.
