An outer ring having an inner peripheral surface as a single concave spherical outer ring raceway, a plurality of spherical rollers provided in double rows between the double row inner ring raceway and the single outer ring raceway, and this spherical surface. A plurality of pockets are provided around the circumference of the bowl-shaped main body to accommodate the rollers so that they can roll freely.
In a double row spherical roller bearing comprising a plurality of cage-shaped cages each having a flange extending radially inward from an edge on the small diameter side of the main body, the main body is connected to a plurality of spherical rollers. The center line is located near the rotation circle drawn in the direction of revolution of the spherical roller, and
The size of each of the pockets is formed to be slightly larger than the generatrix shape of the spherical rollers housed in each pocket, and the end surfaces of the plurality of spherical rollers and the inner surface of the flange and the portion facing the end surface are A feature is that each spherical roller is prevented from falling out from inside the pocket by mutually engaging an engaging protrusion formed on one side with an engaging recess or an engaging hole formed on the other side. Double row spherical roller bearing.
