  • Multi-Barrier COMBI Seal | Mud, Dust, Moisture & Abrasive Debris Protection for Harsh Duty

    Harsh equipment rarely faces only one contaminant. Dry dust can become abrasive paste when mixed with moisture, while mud and grit can attack the same sealing point during the next operating cycle. This multi-barrier COMBI seal is designed for rotating machinery exposed to changing combinations of dust, mud, splash and abrasive debris. Its integrated structure helps reduce external contamination while supporting lubricant retention around shafts, hubs and bearing positions. The seal can be matched to dimensions, lubricant, temperature, rotational speed and installation space for OEM or replacement use. The result is a practical solution for customers who need fewer contamination-related failures across mixed and unpredictable working conditions.

Description
Harsh equipment rarely faces only one contaminant. Dry dust can become abrasive paste when mixed with moisture, while mud and grit can attack the same sealing point during the next operating cycle. This multi-barrier COMBI seal is designed for rotating machinery exposed to changing combinations of dust, mud, splash and abrasive debris. Its integrated structure helps reduce external contamination while supporting lubricant retention around shafts, hubs and bearing positions. The seal can be matched to dimensions, lubricant, temperature, rotational speed and installation space for OEM or replacement use. The result is a practical solution for customers who need fewer contamination-related failures across mixed and unpredictable working conditions.

One sealing solution for changing contamination conditions

Dust, mud, moisture and grit often attack the same rotating interface at different times. This multi-barrier COMBI seal helps protect against mixed contamination while supporting lubricant retention inside the assembly.

Problems Solved

  • Dust becoming abrasive when mixed with moisture.

  • Mud and grit entering during wet operation.

  • Dirty lubricant shortening bearing life.

  • Seal performance changing with weather and terrain.

  • Repeated maintenance across mixed operating conditions.
