PROBLEM TO BE SOLVED: To sufficiently ensure the extracting force and to improve the sealing property in the fitting parts of inner and outer rings with a sealing device. SOLUTION: This sealing device for rolling bearing comprises a dust seal metal ring body 20 having a core ring 22, an elastic seal 24 and an elastic fitting part 26 and a grease seal metal ring body 20 having a core ring 32, an elastic seal 34 an elastic fitting part 36 and an elastic film 38. In this case, a sufficient extracting force can be ensured by the metal fitting of the core rings, and the sealing property can be improved by the elastic fitting parts and the elastic film. The grease seal metal ring body may have an elastic fitting part formed by fixing an elastic material to the core ring in a prescribed thickness and a projection part formed by circumferentially protruding the elastic material. The drawing force can be ensured by engaging the projection part with inner and outer rings. |
