  • Reinforced Contamination Protection COMBI Seal for Construction Machinery Hubs

    Construction machinery works in dust clouds, abrasive soil and wet mud that can overwhelm ordinary hub and shaft seals. When debris reaches the bearing, grease becomes contaminated, wear accelerates and unscheduled downtime follows. This reinforced COMBI seal is designed to strengthen the contamination barrier around rotating hubs and shafts while helping retain lubricant. It is suited to excavators, loaders, compactors, graders and other construction equipment operating on dirty jobsites, helping reduce repeat seal replacement, bearing damage and maintenance interruptions.
