This 6204 2RS C3 deep-groove ball bearing supports rotating shafts in the driveline and material-handling sections of the host harvesting machine. It is a double-sealed, radial bearing with a C3 internal clearance, which allows it to accommodate thermal expansion and light misalignment during prolonged operation. The bearing sits in housings that carry the load from belt pulleys, auger shafts, or roller ends; a seized or worn bearing introduces vibration that can misalign the belt path or overload adjacent bearings. The manufacturer machines the raceways and selects the seal compound to match the original assembly’s running torque and contamination resistance. On installation, press the bearing onto the shaft against a shoulder and ensure the outer ring seats fully in the housing bore; do not apply force through the seals.
