  • Dust & Water Resistant COMBI Seal Protects Wheel Hubs on Off-Road Construction Vehicles

    Designed for off-road construction vehicles, this heavy-duty COMBI seal protects wheel hubs from dust, mud, splash water and abrasive debris. Its metal-cased structure combines a primary oil-retaining lip with reinforced external contamination barriers, helping maintain lubricant cleanliness during repeated exposure to rough terrain, pressure washing and changing weather. The seal supports stable rotation, reduces lip wear and helps prevent premature bearing damage caused by particle ingress or lubricant loss. It is suitable for loaders, articulated dumpers, graders, compactors and other mobile machinery operating in quarries, road projects and earthmoving sites. Materials, dimensions, lip geometry and elastomer compounds can be customized to match hub speed, shaft condition, temperature and lubricant requirements. Compared with standard single-lip seals, the COMBI design provides stronger exclusion performance and longer maintenance intervals. It is a practical replacement or OEM sealing solution for fleets seeking improved reliability, less unplanned downtime and lower wheel-end service costs in demanding outdoor environments.
