ユラ玉軸受。 An outer ring with a double-row raceway surface integrally formed on the inner peripheral surface,
A pair of inner rings each having a raceway surface facing the raceway surface of the outer ring and having both shoulders on its outer peripheral surface, a double row of steel balls interposed between the outer ring and the raceway surfaces separated from each other, and the steel balls. A seal consisting of a pair of retainers that rotatably accommodate and hold the bearings at equidistant positions on the circumference, and a seal that is attached to the inner end of the inner circumference of the outer ring and slides into contact with the outer circumferential surface of the inner ring to seal the bearing. In a double-row angular contact ball bearing, the hermetic seal is composed of an annular seal core and an elastic seal lip attached to the inner diameter end of the seal core, and the seal core is arranged inside both ends of the outer ring. a cylindrical portion fitted to the circumferential surface; a wall portion extending radially from one end of the cylindrical portion on the inner side in the bearing axial direction; and a wall portion inclined outward in the bearing axial direction from the inner diameter end of the wall portion. What is claimed is: 1. A sealed double-row angular contact ball bearing, comprising a flange portion extending as a wall portion, the wall portion receiving the steel balls to prevent separation of the inner ring.
