摘要： A cylindrical roller bearing (1) is provided with an outer race (10), an inner race (20), and a plurality of cylindrical rollers (30). The outer race (10) has on the inner peripheral surface thereof an outer-race raceway surface (11) and a pair of outer-race flanges (12) provided on both axial-direction sides of the outer-race raceway (11). The inner race (20) has on the outer peripheral surface thereof an inner-race raceway (21) and an inner race flange (22) provided on one axial-direction side of the inner-race raceway (21). The cylindrical rollers (30) are arranged between the outer-race raceway (11) and the inner-race raceway (21). The radial-direction height (A) of the outer-race flanges (12) is greater than the radial-direction height (B) of the inner-race flange (22). The radial-direction gap (C) between the outer-race flanges (12) and the inner-race flange (22) is set to 2 mm or less. Consequently, the incidence of edge loading due to a thrust load is minimized and the state of lubrication inside the bearing is improved, which makes it possible to markedly reduce the size of a highly durable cylindrical roller bearing and transmission.

摘要： A dental air turbine (10) includes a turbine blade (12), a rotating shaft (11) which is integrally fixed with the turbine blade (12), and a pair of rolling bearings (13, 14) which rotatably support the rotating shaft (11) with respect to a housing (15). The pair of rolling bearings (13, 14) are arranged back-to-back while fitting inner rings (23, 24) on the rotating shaft (11) such that a preload is applied thereto. Accordingly, it is possible to reduce the sizes of the rolling bearings (13, 14) and to improve the moment rigidity of the rotating shaft (11).

摘要： The invention relates to a ball bearing (1) having an inner race and an outer race. In order to prevent the rotating parts from being damaged when the bearing assembly fails, the invention provides that the bearing has surfaces (14, 15), which are concentric to the rotation axis (6) and of which one is a part of the rotating bearing race and the others are a part of the fixed bearing race. The invention also provides that, during normal operation, the surfaces (14, 15) are situated opposite one another with a relatively narrow gap (24) therebetween and that, in the event of failure, the surfaces (14, 15) function as emergency bearing surfaces.

摘要： A rolling contact device having a shaft (1) adapted to be secured to an element of an apparatus, an outer ring (2) adapted to be in rolling contact with another element of the apparatus, and rolling elements (3) disposed between the shaft (1) and the outer ring (2). An abutting portion (1c)(1d)(2b)(2c) is provided on each of the shaft (1) and the outer ring (2), the abutting portions on the shaft and the outer ring being opposed to each other with a small gap (G) defined therebetween. These abutting portions are arranged such that, when an exessive radial load is applied to the outer ring, the abutting portions are brought into contact with each other to prevent permanent deformation of rolling contact portions of the device.
