Fine abrasive dust can accumulate at the shaft and wear a conventional lip long before planned maintenance. A PU dust deflector provides an added first line of defense against that failure mode.
1. Product Type: Reinforced COMBI shaft seal
2. Core Function: Block abrasive external dust
3. Secondary Function: Retain lubricant
4. Seal Design: Combined primary seal and dust-deflection system
5. Reinforcement: Rigid supported structure
6. Dust Deflector: PU lip option
7. Main Elastomer: NBR or HNBR
8. Dust Lip Material: Polyurethane option
9. Case Design: Reinforced metal case available
10. Size: Custom OD, ID, and width
11. Motion: Rotary shaft
12. Media: Grease/oil retention positions
13. Contaminants: Sand, soil, pollen, chaff, dry dust
14. Environment: Abrasive outdoor service
15. Application: Hubs, axles, gearboxes, drives
16. Machine Types: Tractors, tillers, harvesters, loaders
17. Target Failure: Lip wear from packed dust
18. Lubricant Retention: Helps control grease and oil loss
19. Bearing Protection: Limits particle entry
20. Shaft Protection: Deflects contaminants before contact zone
21. Abrasion Resistance: PU lip suited to abrasive exposure
22. Impact Resistance: Reinforced body supports off-road shock
23. Deformation Control: Stable seal geometry
24. Alignment: Concentric fitting recommended
25. Runout: Must meet equipment tolerance
26. Shaft Finish: Smooth and clean contact surface
27. Installation: Press squarely without lip damage
28. Housing: Clean bore without burrs
29. Orientation: Deflector toward dust source
30. Temperature: Material selected by duty cycle
31. Speed: Suitable when matched to shaft RPM
32. Pressure: Mainly low-pressure rotary use
33. Maintenance Benefit: Reduces dust-driven replacement
34. Service Goal: Protect critical rotating components
35. Replacement Use: Retrofit and overhaul compatible
36. OEM Development: Drawing or sample based
37. Aftermarket: Cross-reference support
38. Inspection: Verify lip, case, and dimensions
39. Customization: Lip material, profile, dimensions
40. Supply: OEM and distributor quantities
41. Quality Control: Visual and dimensional checks
42. Buyer Benefit: Longer protection in abrasive dust
The PU dust-deflector lip tackles the first point of failure: abrasive material reaching the primary lip. It helps keep the sealing zone cleaner so the main seal can do its job longer.
