    摘要: A rolling guide device 160 is provided with a track rail 161 as a track member and a movable member 163 mounted to the track rail 161 to be movable through balls 162. A solid lubricant film is formed to the ball 162 by using a closed magnetic field unbalanced magnetron spattering apparatus (CUMS apparatus). The solid lubricant film has a low friction coefficient at the outermost surface of the film, withstands an inner repeated stress, and has a high adhesion performance. Such solid lubricant film has never been from its inside or boundary portion and wears at the minimum speed from the film surface, so that a reliable and highly ideal solid lubricating function can be attained, and by applying the solid lubricant film having improved adhesion performance and abrasion resistance to the rolling guide device, there can be provided a rolling guide device usable in a specific environmental condition such as an undesirable lubricating environment, high temperature vacuum condition, or an oil-free condition.

    摘要: A rotating, conductive, heat transfer device includes an outer race (14) having an axis (12), an inner race (16) coaxial with the outer race, and a plurality of bearing balls (18 to 38) disposed in a radial direction between the inner race and the outer race. The device (10) also includes a plurality of separators (40 to 58) disposed alternately in a peripheral direction between the bearing balls. A first track (62) and a second track (66) are supported by the inner race (16), for supporting the separators. The inner race has a first, fixed, inner ring portion (92) with a first bearing surface (96), and has a second, separable, inner ring portion (94) with a second bearing surface (98). The outer race (14) has a third bearing surface (100), disposed in a radial direction opposite to the first bearing surface (96) and also has a fourth bearing surface (102), disposed in a radial direction opposite to the second bearing surface (98). The first and second and third and fourth bearing surfaces are in contact with a spherical surface of each bearing ball. A plurality of coil springs (110 to 122) urge the second inner ring portion (92) in an axial direction toward the first inner ring portion (92), thereby applying first and second and third and fourth forces normal to the respective first and second and thrid and fourth bearing surfaces, for providing heat conduction from one race to the other race.

    摘要: A rolling bearing comprises an inner race (1), an outer race (2), and a number of rolling members (3) between. A number of generally cylindrical rolling retainers (4) are arranged between rolling members (3). A pair or rings (5) contact the retainers (4) externally. A pair of covers (6) each defining a support rail (6a) support the retainers (4) internally. Thus the retainers (4) are held in position. In another embodiment, the covers (6) contact the retainers (4) externally, and the rings (5) internally.

    摘要: The invention concerns a contact roller bearing for a vacuum pump comprising a rotor roller bearing ring (12) a coaxial stator roller bearing ring (13) between which are provided rolling elements (14a, 14b, 14c, 14d) housed in succession and urged to roll on respective raceways of the rotor (12) and stator (13) roller bearing rings. The rolling elements comprise an alternating succession of rolling elements (14a, 14c) whereof the outer surface is made of steel and of rolling elements (14b, 14d) whereof the outer surface is made of ceramic, thereby reducing the resistance to acceleration of the contact roller bearing, which limits the friction and wear of the inner annular surface (16) of the contact roller and the corresponding bearing of the rotor.
