A corn header has a plurality of row units disposed adjacent each other. Each row unit has a frame and a gearbox coupled to the frame. The gearbox has a gearing assembly coupled to a rotatable shaft extending from an opening of the gearbox. Each row unit also has a stalk roll coupled to the rotatable shaft and a coupling interface comprising a self-aligning ball or roller bearing assembly. A support bracket is secured to the frame with the coupling interface operably coupling the stalk roll to the support bracket within a defined tolerable limit of misalignment.
