Muddy job sites increase seal maintenance because abrasive dirt reaches the sealing lip, damages the shaft track and contaminates lubricant. The integrated COMBI seal is designed to reduce this exposure by combining oil retention with a dedicated external exclusion barrier. Compared with a standard oil seal, the added protection helps keep mud, dust and splash away from the primary lip. For construction equipment, this can support cleaner bearings, reduce contamination-driven leakage and extend the interval between service events when correct material, size and installation conditions are maintained.
Turn contamination resistance into lower maintenance risk
The benefit of an integrated COMBI seal is not simply an extra lip. It is the separation of two jobs: keeping lubricant in and keeping contamination out.
Helps shield the primary lip from mud
Reduces abrasive particle contact
Supports cleaner lubricant and bearings
Helps prevent shaft-track damage
Can reduce repeat service caused by ingress
For machines that spend most of their time in wet soil, clay and dirty splash, the added exclusion function can address a failure mode that a standard oil seal may not fully control.
