A particle-resistant reinforced COMBI seal designed to reduce unplanned shutdowns caused by dust, grit, sand, and debris contamination. The metal-supported case and multi-lip sealing structure help retain lubricant, protect shafts and bearings, limit abrasive wear, and maintain dependable operation in agricultural and heavy equipment.
This reinforced COMBI radial seal combines an oil-retaining lip with multiple external contamination barriers. It is suitable for axles, hubs, gearboxes, and final drives exposed to airborne particles, soil, mud, and field debris. The rigid case improves housing stability, while customizable elastomers and dimensions help match different temperatures, lubricants, and equipment duty cycles.
