    摘要： A sealed rolling bearing in which a rolling member is disposed in a bearing space formed between an outer race and an inner race to rotate the outer race and the inner race relatively to each other, and rotation seal members are disposed at both ends of the bearing space in the axial direction thereof while a stationary seal member is disposed on the side of the inner race, thereby sealing the bearing space. The bearing is provided with a vent on the side of the inner race for approximating a fluid pressure in the bearing space to an outside fluid pressure by causing the inside of the bearing space to communicate with the outside when the state of fluid in the bearing space and state of the outside fluid have a predetermined relationship.

    摘要： When an inner race (12) rotates at a speed lower than a predetermined speed, a sealing body (27) contacts the sealingface part (21c), but when the inner race (12) rotates at a speed more than the predetermined speed, a contacting pressure to a sealing face part (21c) is reduced or the sealing body (27) is isolated so as to form a non-contacting seal, and therefore, for example, at the low speed, the sealing body (27) forms a contacting seal, thereby to compensate a low speed-low sealing ability of the non-contacting seal such as the labyrinth seal, and on the other hand, at high speed rotation, the sealing body (27) reduces the contacting pressure to the sealing face part (21c), and otherwise separates therefrom to form the non-contacting seal as the labyrinth seal, whereby it is possible to solve the problem of heating or abrasion at the contacting part. Further, a sleeve (122) is mounted on the supporting edge (12a) of the inner race (12), thereby to secure the sealing device (120) without processing a screwing hole in the inner race (12). Moreover, the sleeve (122) is optionally processed with a screwing hole (122a), to thereby easily fix the sealing device (120) by the bolt (124).

    摘要： A sealing device for a roll bearing which includes an outer ring, an inner ring, a rolling element rotatably interposed between the outer and inner rings, and a retainer, comprises a seal holder having a seal holder portion and a seal body attached to the seal holder portion. A portion of the retainer is received in a sealing space defined by the seal holder portion while the portion of the retainer is being disposed outside a range of interference with the seal holder portion. The sealing device further comprises conical surfaces 10 and 19 which are provided as fitting surfaces of a seal holder portion 9a and a seal body 17 fit to the seal holder portion 9a. Accordingly, a space 23 into which one end of a retainer of the bearing is receivable can be formed, and the inside diameter d of the seal holder portion 9a can be reduced.
