This oil seal fits in the header assembly of a combine harvester, where it retains lubricant and excludes contaminants at a rotating shaft interface. It sits between the housing and the shaft, preventing fluid loss and protecting bearings from dirt ingress. A worn or hardened seal allows leakage that can lead to bearing failure and unplanned downtime. This component is manufactured to match the original seal's cross-section and lip geometry, ensuring proper seating in the housing bore and correct contact pressure on the shaft.
