This ball bearing supports rotating shafts within the drive system of a combine harvester or self-propelled forage harvester. It is a double-sealed, deep-groove bearing that retains lubrication and excludes contaminants during operation. A worn bearing produces audible rumble or shaft play, which can lead to misalignment of the driven components and increased load on adjacent gears or belts. The manufacturer machines the bearing to the same internal clearance and seal geometry as the original assembly, so it seats in the housing without shimming. On installation, ensure the housing bore is clean and that the shaft rotates freely after pressing.
