This heavy-duty COMBI seal protects agricultural shafts in demanding field conditions. A reinforced outer shell supports stable installation, while the flexible dust lip blocks mud, crop residue and fine soil particles. The main sealing lip retains oil or grease, helping reduce wear, leakage and repeated replacement.
