PROBLEM TO BE SOLVED: To provide a bearing sealing device capable of keeping fitting accuracy to an outer ring of a core bar, securing a degree of freedom in designing, and free from interference of seal lips when the seal lips are axially overlapped to each other.SOLUTION: In a bearing sealing device 8 including a seal lip member 10 made of an elastic body, including an axial lip 14 fixed to a core grid including a cylindrical portion 9a fitted to an inner diameter portion 2b of an outer ring 2, an outer diameter-side flange portion 9b of an outer diameter direction with respect to one end portion 9aa at a side opposite to a bearing space S, and an inner diameter-side flange portion 9d extended in the inner diameter direction with respect to the other end portion 9ab at a bearing space S side, of the cylindrical portion, and projecting to a side opposite to the bearing space S with respect to the inner diameter-side flange portion, the inner diameter-side flange portion is bent to an inner diameter side through a curved shape portion 9c from the end portion 9ab, the curved-shape portion 9c is provided with a projecting-shape portion 15 made of an elastic body, extended to the bearing space S side, and the projecting shape portion is brought into contact with the adjacent bearing sealing device when the plurality of bearing sealing devices are axially concentrically overlapped, to prevent other regions of the adjacent bearing sealing devices from being brought into contact with each other. |
