とする玉軸受の自動調心シール構造。 In the self-aligning seal structure of a ball bearing, in which a shaft seal and a shielding plate are provided sequentially from the inside on both sides of the ball rolling surface between the bearing rings, a shaft seal and a shielding plate are provided on the outer surface of the bearing seal continuously outward on the circumference. Forming a protruding piece projecting toward the front, and forming an annular recess into which the tip of the protruding piece enters the inner surface of the shielding plate,
A labyrinth gap is formed between the annular recess and the protruding piece, and the side surface of the protruding piece on the outer ring side faces toward the tip and becomes an inclined surface approaching the outer ring, and the amount of entry of the protruding piece into the annular recess is determined by the inner ring and the outer ring. A self-aligning seal structure for a ball bearing, characterized in that the displacement is set to be larger than the amount of displacement when the bearing is tilted to its maximum.
