Cyclic wet and dry contamination can accelerate seal wear because mud packs around the sealing point, dries, then becomes abrasive dust during the next operating cycle. Integrated COMBI Seals are designed to help control this repeating wear mechanism by combining contaminant exclusion with lubricant retention. The integrated format helps protect the primary sealing zone, shaft track, grease and bearings in machinery that repeatedly moves between muddy and dusty conditions. This is useful for construction, agricultural and industrial equipment where seal life varies because exposure changes by shift or season. Correct application requires matching seal dimensions, material, shaft finish, speed, temperature and pressure to real operating conditions.
