Seal failures in muddy and dusty machinery often follow the same pattern: debris reaches the lip, grease becomes contaminated, the shaft track wears, leakage begins and the bearing eventually needs attention. Integrated COMBI Seals are designed to interrupt this chain by combining external contaminant exclusion with internal lubricant retention. The integrated architecture helps shield the primary sealing zone and reduce the number of paths available to mud, fine dust and abrasive grit. For maintenance teams, this targets real failure modes rather than simply replacing a leaking seal with the same design. Applications include hubs, axles, shafts and bearing housings in construction, agricultural and industrial equipment. Always verify dimensions, speed, temperature, pressure, material compatibility and shaft condition before installation.
