外輪付き円筒ころ軸受

Japanese Patent JP7472544

B2

In a cylindrical roller bearing (10) with an outer ring, an annular portion (32) on the other side in an axial direction of the retainer (30) is provided with a plurality of protrusion portions (40) each having an engaging portion (41) protruding radially outward with respect to an inner circumferential surface of an inward flange portion (15). Further, when an axial distance between a flat surface on one side in the axial direction of an outward flange portion (14) and an end surface on the one side in the axial direction of the annular portion (31) on the one side in the axial direction is set as A, and an axial distance between a flat surface on the other side in the axial direction of the inward flange portion (15) and a side surface on the one side in the axial direction of the engaging portion (41) is set as B, B is greater than A. Accordingly, it is possible to provide a cylindrical roller bearing with an outer ring which can prevent the retainer from falling off from the outer ring with good assembly workability without increasing the number of components, and which takes into consideration insertion workability of the cylindrical rollers and prevention of the cylindrical rollers from falling off from the retainer.
