Fine dust can pass through weak sealing points, mix with lubricant and become an abrasive paste that damages shafts and bearings. Dust-exclusion COMBI seals help keep fine particles away from the contact zone while retaining lubricant, reducing the risk of shaft scoring, contaminated grease and premature component wear.
Fine dust becomes abrasive once it mixes with grease. Dust-exclusion COMBI seals help stop airborne particles before they enter the shaft and bearing interface. Their integrated sealing structure supports cleaner lubrication and reduces the abrasive wear that leads to shaft grooves, leakage and repeat seal failure.
