Premium Reinforced Dust Contamination Proof COMBI Seal Protect Wheel Hub Bearings

Wheel Hubs Live Next To The Contaminant Source

Tires throw dust, water and grit directly toward rotating hub interfaces. The Premium Reinforced Dust Contamination Proof COMBI Seal helps keep that debris away from the lubricated bearing cavity. A COMBI Seal in a wheel hub must cope with continuous rotation, changing road or field conditions and the movement created by bearing load.

Once dust contamination reaches a bearing, particles can pit the raceways and increase heat. The Premium Reinforced Dust Contamination Proof COMBI Seal reduces the external particle load before it reaches grease or oil.

Bearing Adjustment Affects Seal Contact

Excessive hub play moves the shaft or sealing track relative to the lip. The Premium Reinforced Dust Contamination Proof COMBI Seal cannot maintain ideal contact if the bearing adjustment allows excessive movement. A COMBI Seal replacement should therefore be combined with a check of bearing preload or end play according to the equipment specification.

If dust contamination appears only on one side of the seal, inspect hub alignment and bearing condition. The Premium Reinforced Dust Contamination Proof COMBI Seal should show a consistent contact band when the rotating assembly is stable.

Inspect The Hub Track Before Replacement

A worn hub or shaft track can quickly damage a new COMBI Seal. The Premium Reinforced Dust Contamination Proof COMBI Seal needs a smooth surface without deep grooves, corrosion or burrs. Measure the track and repair or sleeve it when the design permits.

Clean old grease and abrasive residue from the housing before fitting the Premium Reinforced Dust Contamination Proof COMBI Seal. Any particles left during assembly can create dust contamination from the protected side of the lip.

Watch Heat, Grease Condition And Leakage

A COMBI Seal should be inspected when a hub runs hotter than comparable wheels. Heat can indicate bearing damage, incorrect adjustment or excess friction. The Premium Reinforced Dust Contamination Proof COMBI Seal should help keep lubricant inside without creating an abnormal temperature rise.

Wet dust around the hub is an early warning. The Premium Reinforced Dust Contamination Proof COMBI Seal should prevent oil or grease from escaping outward because leaked lubricant attracts even more abrasive material.

Protect The Bearing, Not Just The Seal

Maintenance teams should inspect the complete hub system: bearing play, lubricant condition, track wear, breather or pressure paths and external shields. A COMBI Seal is the barrier, but the bearing assembly determines the movement it must follow. The Premium Reinforced Dust Contamination Proof COMBI Seal works best when those conditions are within specification.

When dust contamination is stopped before it reaches the bearing cavity, the Premium Reinforced Dust Contamination Proof COMBI Seal helps reduce race pitting, lubricant loss, overheating and repeated hub teardown on farm machinery, trailers and mobile equipment.
