This deep-groove ball bearing supports a rotating shaft within the drive system of a harvesting machine. It is a single-row bearing with two rubber seals and a C4 internal clearance, meaning the radial play is greater than standard to accommodate thermal expansion or misalignment in the driveline. The bearing sits in a housing that aligns the shaft with the upstream gearbox and downstream driven component. A worn bearing produces audible rumble, shaft wobble, or increased operating temperature, which can lead to seal failure and contamination of the lubricant. The manufacturer machines the raceways and selects the steel grade to match the original assembly's load rating and fatigue life. On installation, press the bearing onto the shaft using the inner ring only and ensure the housing bore is clean to avoid brinelling the outer race.
