A heavy-duty COMBI seal with an advanced dust-barrier design for machinery operating on dusty worksites. The reinforced case and multiple protective lips help retain lubricant, block fine dust, sand, soil, and debris, and protect shafts, bearings, hubs, and drive components from contamination-related leakage and wear.
This reinforced COMBI radial shaft seal is designed for agricultural and off-highway equipment working in dusty construction zones, farms, quarries, and material-handling sites. Its primary lip retains oil or grease, while advanced auxiliary lips form an external contamination barrier. The rigid case supports stable installation, and custom dimensions and compounds are available for specific equipment requirements.
