It installs directly onto the axle spindle to keep lubricant in and contaminants out, protecting the wheel bearings from premature failure. You replace this seal during wheel-end service or if you notice a hub leak, as a failed seal can lead to expensive bearing damage and downtime. Its HNBR-PTFE lip and rubber outer diameter provide superior durability and easier hub cleaning compared to traditional seals.
