  • Long-Life Reinforced COMBI Seal for Wheel Hubs Exposed to Sand and Water

    Wheel hubs exposed to road grit, standing water and pressure washing can suffer rapid bearing contamination and repeated seal leakage. This long-life reinforced COMBI seal combines lubricant retention with an external dirt barrier to help protect hub assemblies in commercial, agricultural and off-road service. Its stable reinforced body and multi-lip contact design reduce contaminant entry, support reliable rotation and help extend maintenance intervals without changing the surrounding hub structure.

Description
Wheel hubs exposed to road grit, standing water and pressure washing can suffer rapid bearing contamination and repeated seal leakage. This long-life reinforced COMBI seal combines lubricant retention with an external dirt barrier to help protect hub assemblies in commercial, agricultural and off-road service. Its stable reinforced body and multi-lip contact design reduce contaminant entry, support reliable rotation and help extend maintenance intervals without changing the surrounding hub structure.

Long-Life Reinforced COMBI Seal for Wheel Hubs

Developed for hubs that repeatedly encounter sand, road spray, water crossings and cleaning jets. The seal helps prevent abrasive particles and moisture from reaching the bearing cavity while reducing lubricant loss.

Customer Pain Points Solved

  • Water enters the hub after washing

  • Sand damages standard sealing lips

  • Grease escapes during long operation

  • Bearing noise returns after replacement

  • Hub servicing is too frequent

  • Seal movement causes uneven wear
