A method for lubricating a radial bearing of a food cutter assembly is disclosed. The method can include receiving a supply of water at a housing for rotationally mounting a spindle body having a rotational axis, where the housing includes a radial bearing proximate to a thrust disc of the spindle body. The thrust disc can include opposing surfaces extending radially from the rotational axis of the spindle body and a circumferential surface between the opposing surfaces. The water can be directed through fluid passages extending from a port in the housing through the radial bearing to the spindle body and across the opposing surfaces and the circumferential surface to the spindle body. The spindle body may be rotated while the water is directed through the fluid passages to create a water film between the housing and the spindle body that reduces friction between the housing and the spindle body.
