Fix the Root Cause of Mud-Dust Seal Failures

Changing bearings without correcting the sealing system can turn maintenance into a repeating cycle. Integrated COMBI Seals address the external contamination path that often drives grease pollution, abrasive wear and early bearing damage.

Product Attributes

• Product type: integrated rotary seal

• Core solution: exclusion plus lubricant retention

• Customer pain point: recurring bearing and seal replacement

• Failure mode targeted: contamination-driven wear

• Mud defense: helps resist wet packed debris

• Dust defense: helps block fine airborne particles

• Abrasive defense: reduces particle contact at critical surfaces

• Lubricant protection: helps retain grease

• Bearing protection: lowers contamination exposure

• Shaft protection: helps reduce scoring

• Primary sealing zone: shielded by integrated geometry

• External exclusion: designed for dirty environments

• Ingress control: reduces mud and dust entry paths

• Leakage control: supports lubricant containment

• Wear objective: slow contamination-related wear

• Reliability objective: extend predictable service intervals

• Downtime objective: reduce repeat repair events

• Maintenance objective: solve causes rather than symptoms

• Spare-part objective: reduce frequent replacement consumption

• Retrofit suitability: depends on installation envelope

• Application: shafts, hubs, axles and bearing positions

• Equipment: construction, farm and industrial machinery

• Environment: muddy and dusty severe service

• Duty: heavy and repetitive contamination exposure

• Rotation: rotary shaft use

• Installation: press-fit or application-specific mounting

• Concentricity: proper alignment required

• Housing fit: verify bore dimensions and condition

• Shaft fit: verify diameter and running surface

• Design: all-in-one COMBI configuration

• Material: application-selected elastomer and reinforcement

• Temperature: select to actual operating range

• Speed: select to shaft speed and lip velocity

• Pressure: confirm system pressure conditions

• Size: specify shaft ID, housing OD and width

• Surface finish: compatible finish supports seal life

• Installation care: avoid lip damage and contamination

• Inspection: check seal, shaft track and housing

• Service cleaning: remove mud before inspection

• Replacement signs: leakage, cracking, hardening or worn track

• Storage: clean, dry, protected storage

The best seal upgrade begins with failure evidence: contamination type, shaft condition, grease condition, operating speed and installation geometry.
