Abrasive mud can damage both sides of the sealing interface: the flexible lip and the rotating shaft track. Once scoring develops, repeated leakage can continue even after seal replacement.
An integrated COMBI seal helps intercept dirt before it reaches that contact zone.
Helps reduce abrasive lip wear
Protects shaft sealing tracks
Limits mud at the primary seal interface
Supports cleaner lubricant
Useful for equipment with repeat wear failures
For muddy job sites, protecting the contact surface can be as important as choosing the correct seal material and dimensions.
