The invention provides equipment for supplying lubricant for a rolling roll of a rolling mill comprising a plurality of spray nozzles for spraying a lubricant and a gas in a particulate or atomized state to the rolling roll, a lubricant feed device for feeding the lubricant to the spray nozzles, and a gas feed device for feeding the gas to the nozzles. The amount of lubricant supplied from side spray nozzles is larger than the lubricant feed rate from the center spray nozzle, and the amount of lubricant supplied from the spray nozzles between these side spray nozzles and center spray nozzle is not more than the amount of lubricant from the side spray nozzles and not less than the lubricant from the center spray nozzle. Thus uneven wear and roughness is reduced in the axial direction of the rolling roll.
