Problem: Abrasive particles cut or wear conventional dust lips, allowing contamination to reach the shaft and oil lip.
Solution: A PU dust-lip option provides strong abrasion resistance, while the reinforced case and inner oil lip maintain sealing stability.
Improved dust-lip abrasion resistance
Protects the primary sealing edge
Reduces contaminant-driven shaft damage
