転がり軸受装置を構成する回転側部材の周面と静止側部材の周面との間に存在して複数個の転動体を設置した空間の端部開口を塞ぐ為、上記静止側部材に保持したシールリングと、上記回転側部材に固定したスリンガとを備え、上記シールリングを構成する弾性材製のシールリップの先端縁を上記スリンガの表面に全周に亙って摺接させたシール装置に於いて、上記スリンガをステンレス鋼板により造ると共に、上記シールリングを構成する弾性材をアクリロニトリルブタジエンゴムを含有するものとし、上記スリンガの表面のうちの少なくとも上記シールリップと摺接する部分の表面粗さを、中心線平均粗さで０．３μｍ以下とすると共に、最大高さで１．２μｍ以下とした事を特徴とするシール装置。In order to close an end opening of a space in which a plurality of rolling elements are installed between a peripheral surface of a rotating side member and a peripheral surface of a stationary side member constituting the rolling bearing device, the stationary side member is held. A seal device comprising a seal ring and a slinger fixed to the rotating side member, wherein the tip edge of the seal lip made of an elastic material constituting the seal ring is in sliding contact with the surface of the slinger over the entire circumference. The slinger is made of a stainless steel plate, and the elastic material constituting the seal ring contains acrylonitrile butadiene rubber. The surface roughness of at least the portion of the surface of the slinger that is in sliding contact with the seal lip is determined. The sealing device is characterized by having a center line average roughness of 0.3 μm or less and a maximum height of 1.2 μm or less. 表面粗さを、中心線平均粗さで０．１μｍ以上とすると共に、最大高さで０．４５μｍ以上とした、請求項１に記載したシール装置。 The sealing device according to claim 1, wherein the surface roughness is 0.1 μm or more in terms of centerline average roughness and 0.45 μm or more in terms of maximum height .
