Single-lip seals can perform well in cleaner conditions, but muddy sites add packed dirt, grit and splash that may attack the sealing edge directly. This Integrated COMBI Seal adds multiple contamination barriers around the shaft while retaining lubricant, giving heavy equipment a more robust solution where recurring dirt ingress, lip wear and bearing contamination make basic sealing unreliable.
Problem solved: Upgrades vulnerable single-lip sealing where severe mud and abrasive debris repeatedly cause contamination.
