  • Water-and-Dust Barrier COMBI Seal for Outdoor Rotating Shaft Protection

    Outdoor rotating shafts are continuously exposed to rain, airborne dust, condensation and cleaning water. When a conventional oil seal cannot block both moisture and contamination, bearings corrode, lubricant degrades and equipment becomes unreliable. This water-and-dust barrier COMBI seal combines a reinforced lubricant-retention lip with an external exclusion system to help protect pumps, fans, drives and outdoor machinery. Custom materials and dimensions support varied temperature, shaft and housing requirements.

Description
Outdoor rotating shafts are continuously exposed to rain, airborne dust, condensation and cleaning water. When a conventional oil seal cannot block both moisture and contamination, bearings corrode, lubricant degrades and equipment becomes unreliable. This water-and-dust barrier COMBI seal combines a reinforced lubricant-retention lip with an external exclusion system to help protect pumps, fans, drives and outdoor machinery. Custom materials and dimensions support varied temperature, shaft and housing requirements.

Water-and-Dust Barrier COMBI Seal for Outdoor Shafts

Developed for rotating equipment exposed to rain, condensation, airborne dirt and wash-down water. The combined design helps retain lubricant and reduce moisture-related corrosion around bearing locations.

Customer Problems Solved

  • Rainwater reaches bearing cavities

  • Condensation contaminates grease

  • Outdoor dust damages sealing lips

  • Wash-down water bypasses basic seals

  • Corrosion shortens bearing life

  • Unplanned outdoor repairs are difficult
