摘要： In a seal for a rolling bearing, the seal has a molding member formed from a rubber material, the molding member including a lip portion, the molding member having 0.3 to 5.0 MPa of tensile stress at 10% strain and no less than 50% of elongation at break after the rubber material is subjected to an accelerated air aging at 130.degree. C. for 1000 hours. The rubber material includes the nitrile rubber compound containing a raw-material rubber, with respect to 100 weight parts of the raw-material rubber, 0.3 to 5.0 weight parts of an age resistor, and 0.3 to 5.0 weight parts of at least one secondary age resistor. The seal prevents grease enclosed in the rolling bearing from leaking out, the lip portion from being broken, and dust resistance from being lowered even in the case where the rolling bearing is used in a high-temperature environment.

摘要： A rolling bearing with the sealing device which has a fitting groove and sealing device with a mounting portion. The fitting groove formed on the inner peripheral surface of an outer ring. An outside surface of the fitting groove tilts at 5 to 30 degrees with respect to an radial direction of the bearing. An inside surface of the fitting groove tilts at a tilt angle smaller than that of the outside surface. A total of these tilt angles is 35 degrees or more. The mounting portion has a base portion contacting the inside surface and a portion projecting toward the outside surface of the fitting groove from the base portion, and the mounting portion is thinnest at a front end portion of the projecting portion.
