Excavators, loaders, graders and other construction machines face repeated mud splash, abrasive dust and high contamination loads around hubs, axles and rotating shafts. When a conventional seal cannot keep dirt out, grease becomes contaminated, shaft tracks wear and bearing service arrives early. Integrated COMBI Seals provide an upgrade path by combining external exclusion with internal lubricant retention in one compact design. The goal is fewer field failures, cleaner grease, better shaft protection and more predictable maintenance intervals. This makes the solution useful for heavy equipment fleets trying to reduce wheel-end and bearing downtime. Final selection should match the machine’s shaft diameter, housing bore, seal width, running speed, temperature, pressure and surface condition.
