This bearing is a double-sealed, deep-groove ball bearing with a C4 internal clearance rating. It supports a rotating shaft within the driveline of a self-propelled forage harvester, maintaining alignment under radial and moderate axial loads. The 2RS contact seals retain grease and exclude contaminants from the rolling elements. A bearing with excessive clearance or seal failure allows shaft deflection, which can cause vibration and premature wear on adjacent gears or pulleys. As an original-manufacturer component, it is produced to the same raceway geometry and seal-land dimensions as the bearing fitted during assembly, so no shimming or housing modification is required during replacement. On installation, ensure the shaft and housing bore are clean and free of burrs.
