  • COMBI Seal Premium Reinforced Multi-Particle Dust Defense Against Pollen Sand and Soil

    Fine pollen can migrate through small gaps, sand can abrade the lip, and soil can pack around the shaft until the sealing interface is overloaded. This premium reinforced COMBI seal is designed to handle mixed agricultural contamination with a stable supported body, NBR or HNBR main sealing options, and an optional PU dust-deflector lip for abrasive duty. It helps keep particles away from bearings, reduce shaft wear, and retain lubricant in hubs, axles, gearboxes, and transmission positions. Custom sizes are available for OEM and replacement applications across agricultural and off-road machinery.
