This bearing is a double-sealed, deep-groove ball bearing with a C4 internal clearance, designed for use in the driveline or rotor assembly of a self-propelled forage harvester. It supports a rotating shaft and accommodates radial and moderate axial loads while the wider-than-normal internal clearance allows for thermal expansion during sustained high-load operation. A worn bearing produces audible rumble and shaft play, which can lead to misalignment of the driven components and accelerated wear on adjacent seals and housings. The original manufacturer's seal geometry matches the housing bore to exclude crop debris and moisture. On installation, ensure the shaft journal is clean and free of burrs, and press the bearing onto the shaft using the inner ring only to avoid brinelling the raceways.
