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 1):
A rotary seal comprising:\n a core metal; a seal member having a base portion joined to the core metal and a seal lip portion; and a slinger having at least one sliding contact surface with which the seal lip portion comes in contact, wherein the at least one sliding contact surface has a surface condition that an arithmetic average roughness Ra satisfies 0.3 \u03bcm\u2264Ra\u22641.0 \u03bcm, a skewness of roughness curve Rsk satisfies Rsk\u2264\u22121, and an average length of roughness curve element RSm satisfies 100 \u03bcm\u2264RSm, Ra, Rsk, and RSm defined by JIS B 0601:2013.
