The invention discloses a cylindrical roller bearing of a lubricating structure and a matched pressing nut, belongs to the bearing field, and particularly relates to a cylindrical roller bearing. Theinvention aims to solve the problem that an existing bearing and an existing roller body are poor in lubricating effect. The cylindrical roller bearing of the lubricating structure and the matched pressing nut comprise the cylindrical roller bearing and the matched pressing nut, wherein the cylindrical roller bearing is embedded into the rolling body; the cylindrical roller bearing is pressed by the matched pressing nut; ring-shaped grooves are formed in the two sides of the cylindrical roller bearing; and straight oil holes are formed to communicate with the ring-shaped grooves; inclined oilholes are utilized for enabling the ring-shaped grooves to communicate with a rolling path of the rolling body; and a ring-shaped oil storage groove is formed in one side of the matched pressing nut,and an oil conveying hole i
