Mud contamination can lead to lip wear, oil leakage, bearing exposure and unplanned repair. The COMBI seal adds exclusion stages so external debris is less likely to reach the primary sealing contact.
1. Product: Integrated COMBI seal
2. Goal: Reduce contamination-related breakdowns
3. Pain point: Repeat leaks after muddy shifts
4. Motion: Rotary
5. Main function: Oil retention
6. Second function: Dirt exclusion
7. Contaminants: Mud/grit/water/dust
8. Architecture: Multi-lip integrated
9. Oil lip: Dedicated
10. Exclusion barriers: Multiple
11. Leak-risk control: Reduce debris at contact line
12. Bearing-risk control: Helps limit contamination path
13. Abrasion control: Enhanced
14. Shaft protection: Helps reduce scoring
15. Mud resistance: Heavy-duty intent
16. Equipment: Excavators/loaders/off-road drives
17. Positions: Hubs/axles/gearboxes/final drives
18. Housing: Press-fit
19. Shaft interface: Profile dependent
20. Elastomer: NBR/HNBR/FKM
21. Case: Steel options
22. Spring: By design
23. Oil compatibility: Verify
24. Grease compatibility: Verify
25. Pressure: Check case pressure
26. Speed: Match RPM
27. Temperature: Match compound
28. Bearing play: Check before install
29. Runout: Within spec
30. Shaft finish: Controlled
31. Bore: Clean/burr-free
32. Installation: Square press
33. Orientation: Correct sides
34. Reuse: No
35. Inspection: Leak/debris/shaft track
36. Retrofit: Verify space
37. Custom size: Available
38. OEM match: Number/sample/size
39. QC: Dimension/lip/case
40. Order data: ID/OD/width/RPM/media
41. Maintenance method: Pair seal change with root-cause check
42. Downtime benefit: Lower repeat intervention risk
Maintenance note: A contamination seal cannot correct loose bearings, blocked breathers or deep shaft grooves. Fix those failure contributors at the same repair event to avoid another breakdown.
