Sticky mud and fine abrasive particles can quickly wear ordinary dust lips, opening a path toward the main oil seal and bearing. This Integrated COMBI Seal can use a PU dust lip to strengthen the outer contamination barrier where abrasion is severe. The combination helps keep mud, sand and grit away from the primary sealing lip, supporting cleaner lubricant and longer service life in harsh field equipment.
Problem solved: Strengthens the first line of defense where abrasive mud rapidly damages conventional dust lips.
