This metal roller bearing supports the shaker assembly in a forage rake. It rotates on its inner race to allow the shaker arms to move freely as the rake tines engage the crop. A worn bearing produces play in the shaker linkage, leading to uneven tine movement and reduced pickup efficiency. The original manufacturer’s race and rolling-element geometry match the housing bore and shaft diameter of the rake frame, so no shimming or adapter sleeves are required during replacement.
