Claims

[Claims for Utility Model Registration] (1) Grease retaining plates are attached to both ends of the outer ring in a cylindrical roller bearing, and the grease retaining plate is formed into a tapered portion that slopes outward from the inner circumference of the outer ring toward the inner ring. A lubrication device for a cylindrical roller bearing, which is formed by a weir extending from the tip of the tapered portion toward the inner ring side, and the outer circumferential surface of both ends of the retainer in the cylindrical roller bearing is formed into a tapered surface corresponding to the tapered portion. (2) The greasing device for a cylindrical roller bearing according to claim 1, wherein the column portion located between each pocket of the cage in the cylindrical roller bearing is formed in a tapered shape protruding toward the inner ring.
