A contamination-guard COMBI seal designed to protect heavy-equipment axle lubricant from dust, soil, mud, water splash, and abrasive debris. Its reinforced case and multi-lip arrangement help separate the internal lubricant from external contamination, reduce oil degradation, and protect shafts, bearings, hubs, and axle components.
This reinforced COMBI axle seal combines a primary lubricant-retaining lip with external contamination barriers for demanding agricultural and off-highway machinery. The rigid metal case supports stable installation, while multiple protective lips help keep dirt away from the shaft interface. It is suitable for axle ends, wheel hubs, final drives, and gear housings. Custom sizes and materials are available.
