Claims

[Claims for Utility Model Registration] An outer ring, an inner ring, rolling elements, and a two-pronged bearing seal whose outer circumference is fixed to the outer ring and whose inner circumference consists of a first lip and a second lip. A sealing device for a bearing comprising: a groove formed in the inner ring including a conical surface extending axially inward from an end surface of the inner ring and an upright surface extending radially outward from an inner end of the conical surface; The first lip of the seal is in sliding contact with the upright surface from the outside in the axial direction so as to produce a shimmy, while the second lip of the bearing seal is in sliding contact with the conical surface from the inside in the axial direction. Bearing sealing device.
