Integrated COMBI Seals – Mud-Prone Site Protection for Dusty Equipment

Designed for machines working where wet mud and airborne dust attack sealing points at the same time. The integrated barrier helps protect bearings, retain lubricant, and lower maintenance frequency.

Customer Pain Point

Wet mud packs around ordinary seals while fine dust follows the shaft path into grease. The result is abrasive wear, dirty lubricant, hot bearings and repeated maintenance.

How This COMBI Seal Helps

The integrated design places contamination-exclusion features ahead of the main sealing lip, helping stop mud, dust and grit before they reach lubricated rotating parts.

Typical Applications

Mud-prone construction, industrial and off-road equipment.
