Abstract:
There is provided a rotary seal having uneven surfaces formed on sliding contact surfaces of a slinger with which seal lip portions of a seal member come in contact, in which wear of the seal lip portions is reduced, resulting in increased reliability. The rotary seal  1  includes: a core metal  3 ; the seal member  4  having a base portion  4 A joined to the core metal  3  and the seal lip portions  4 B,  4 C, and  4 D; and the slinger  2  having the sliding contact surfaces A and B with which the seal lip portions  4 B,  4 C, and  4 D come in contact, in which each of the sliding contact surfaces A and B is in such a surface condition that an arithmetic average roughness Ra satisfies 0.3 μm≤Ra≤1.0 μm, a skewness of roughness curve Rsk satisfies Rsk≤−1, and an average length of roughness curve element RSm satisfies 100 μm≤RSm, Ra, Rsk, and RSm defined by JIS B 0601:2013.

Claim (Index 2):
The rotary seal according to  claim 1 , wherein\n the core metal is formed by a cylindrical core metal cylinder and a core metal flange extending radially inward from one end in an axial direction of the core metal cylinder, the slinger is formed by a cylindrical sleeve and a flange extending radially outward from one end in the axial direction of the sleeve, the at least one sliding contact surface includes a first sliding contact surface and a second sliding contact surface, and the seal lip portion of the seal member has an axial lip that comes in sliding contact with the first sliding contact surface on an inner surface of the flange of the slinger and a radial lip that comes in sliding contact with the second sliding contact surface of an outer peripheral surface of the sleeve of the slinger.
