There is provided a lubricating method for a rolling bearing assembly capable of achieving a reliable lubrication and exhibiting a stable temperature rise. The method is for supplying a lubricant oil to the rolling bearing assembly during the operation thereof, in which in order to keep the temperature of a rolling bearing assembly ( 103 ) within a predetermined tolerance, the amount of the lubricant oil to be supplied during the operation is automatically or manually adjusted by means of a supply adjusting unit ( 102 ). Supply of the lubricant oil is performed in the form of an air/oil mixture by the use of a lubricant supply unit ( 101 ). The amount of the lubricant oil supplied varies depending on the rotational speed of the rolling bearing assembly ( 103 ). Change of the amount of the lubricant oil supplied depending on the rotational speed of the rolling bearing assembly ( 103 ) is carried out based on a result of sampling of data showing increase in temperature of the rolling bearing assembly ( 103 ) depending on the rotational speed thereof under a plurality of different lubricating conditions in which a different amount of the lubricant oil to be supplied is employed.
