摘要： A roller and guide assembly for use in an actuating seat suspension having a roller assembly comprised of a first and second roller that articulate on upper and lower guide surfaces formed by a channel. The first roller rotatingly engages the lower guide surface and the contact between the first roller and guides surface permits the roller to move horizontally along the guide surface while preventing the downward movement of the roller assembly. The second roller rotatingly engages the upper guide surface an the contact between the roller and guide surface permits the roller to move horizontally along the guide surface while preventing the upward movement of the roller assembly.

摘要： A guide mechanism is provided with first guide rails each having a circular arc-shaped cross section to be installed to first long grooves each having a circular arc-shaped cross section formed on an inner wall surface of a frame, and second guide rails each having a circular arc-shaped cross section to be installed to second long grooves each having a circular arc-shaped cross section formed on side surfaces of a slider opposed to the inner wall surface of the frame. Accordingly, the arrangement of ball-rolling grooves in the slider can be performed more freely, and it is possible to mitigate the concentration of stress exerted by external force.

摘要： When working a linear guide rail having one or more raceway grooves 2 on the side surfaces thereof, using rotary dies each including on the circumferential portion thereof a projection-shaped working portion matched in shape to the raceway groove 2, the raceway grooves 2 are rolled onto a rail blank work W. Since the raceway grooves 2 can be rolled with high accuracy by a single working step, the working time of the raceway grooves as well as the working cost thereof can be reduced.

摘要： A ball-type anti-friction device which has a housing, a ball cage mounted within the housing for movement relative to the housing between a lower inactive position and an upper active position. The ball cage contains a relatively large ball mounted on relatively small bearing balls so that when the ball cage is in the lower or inactive position, the large ball is below the top surface of the housing and when the ball cage is in the upper or active position, the ball extends above the top surface of the housing. In a first embodiment, the housing contains a double acting fluid drive system. The fluid drive system includes two fluid chambers and a piston connected to the ball cage. The piston is selectively actuated by selective pressurization of the two fluid chambers. In a second embodiment, the ball cage is actuated by a single acting fluid drive system. A piston is connected to the ball cage and is biased downwardly to normally maintain the ball cage and large ball in the lower or inactive position. The housing contain a single fluid chamber which, when pressurized, causes the ball cage and large ball to move to the active or upper position in opposition to the biasing means.

摘要： A linear roller bearing includes a bearing cage retaining parallel rollers in a linear configuration. Side portions of the bearing cage extend laterally to form a mechanical interlock with an adjacent similar bearing cage such that, when two or more bearing cages are positioned about an inner tubular member for guided axial movement relative to a coaxial outer tubular member, the mechanical interlock prevents relative axial movement of the adjacent bearing cages. Adjacent bearing cages may be identical or of differing configuration provided a mechanical interlock preventing relative axial movement results. The linear roller bearing may include inner and outer races, or, alternatively, the tubular members may be formed with integral raceways.
