  • Dual-Lip Reinforced Dust COMBI Seal for Off-Road Vehicle Wheel Hubs

    Off-road hubs face repeated exposure to mud, sand, water crossings and impact vibration. Standard seals can allow contamination into the bearing cavity or lose grease under harsh use. This dual-lip reinforced COMBI seal creates separate lubricant-retention and dirt-exclusion zones to help protect wheel hubs, reduce bearing damage and extend service intervals. It is suitable for utility vehicles, agricultural transporters, trailers and other equipment operating beyond paved roads.

Dual-Lip Reinforced Dust COMBI Seal for Off-Road Hubs

Engineered for wheel hubs operating in mud, sand, standing water and vibration. The combined sealing system helps retain grease and reduce abrasive contamination entering the bearing area.

Customer Problems Solved

  • Mud reaches hub bearings

  • Water crossings wash grease away

  • Sand damages single-lip seals

  • Vibration loosens weak seal structures

  • Frequent hub rebuilds increase cost

  • Unexpected bearing failure stops vehicles
