Construction machinery rarely works in clean conditions. Mud, quarry dust and abrasive grit can attack hub sealing points every shift. This COMBI seal helps create an integrated barrier that limits external contamination while supporting lubricant retention inside the hub assembly.
1. Product Type: Construction equipment COMBI seal
2. Primary Application: Wheel hub contamination protection
3. Core Function: External dirt exclusion

5. Mud Resistance: Designed for wet jobsite conditions
6. Dust Resistance: Designed for quarry and earthwork dust
7. Grit Resistance: Helps block abrasive particles
8. Splash Resistance: Supports wet outdoor operation
9. Bearing Protection: Helps reduce contaminant entry
10. Hub Protection: Helps maintain cleaner wheel-end conditions
11. Grease Retention: Configurable for hub grease service
12. Oil Retention: Configurable where oil lubrication is specified
