The invention discloses a bearing sealing structure which comprises a rack square tube (1), a casing (2), a supporting wheel shaft (3), a sleeve (5), an oil seal (6), a bearing (7) and a supporting wheel (8), wherein the end surface, far from the casing (2), of the sleeve (5) is provided with a sealing groove for placing an O-shaped sealing ring (4); and the sealing groove is a triangular groove which guarantees axial and radial sealing of the O-shaped sealing ring (4). According to the sealing structure with the special structure, the sealing groove is processed in the right end surface of the sleeve, so that the contact area between the left end of the sleeve and the casing is increased by about once, and therefore, the end surface is prevented from being weakened, and stress on the casing and the sleeve is obviously improved; meanwhile, by virtue of the set triangular sealing groove, the O-shaped sealing ring achieves axial and radial sealing, so that the sealing reliability is increased; the O-shaped sealing ring can be protected, so that the O-shaped sealing ring is prevented from being cut during assembling, and the service life of the O-shaped sealing ring is prolonged.
