摘要： A cage segment for a rolling-element bearing cage includes first and second side elements connected by a bridge extending in a longitudinal direction. A first attaching element on the first side element extends away from the bridge in a first direction parallel to the longitudinal axis and a second attaching element on the second side element extends away from the bridge in a second direction parallel to the longitudinal axis. The first and second attaching elements are configured to receive a wire or cable for connecting the cage segments to other cage segments, and the first attaching element is offset from the longitudinal axis in a first direction by a first distance and the second attaching element is offset from the longitudinal axis in a second direction opposite the first direction by a second distance.

The main body member has position reference holes formed therein so as to serve as position references for the direction change pipes, respectively, whereas the direction change pipes have positioning protrusions formed thereon so as to be press-fitted into the position reference holes, respectively. Further, the direction change pipes include rotation restriction protruding portions.

摘要： A connector for a linear guideway is integrally formed by injection molding. The mold assembly of making the connector includes an upper mold, a lower mold and a pin. The variable cross section design of the pin enables the connector to have a plurality of ring-shaped portions with more than two different axial thicknesses, so that the distances between the respective rolling elements are different, and the frequencies of the respective rolling elements are also different, and as a result, the resonance sound pressure caused by the linear guideway and the machine are reduced. In addition, the variable cross section design of the pin reduces the manufacturing difficulty of making a relatively long connector.

摘要： A roller guiding apparatus for use in linear guiding portions of a variety of kinds of industrial machines such as machine tools and the like is provided for guiding rollers which rollingly travel along a pair of opposed roller-rolling surfaces formed on a traveling rail and a movable body so as to move the movable body along the traveling rail. The apparatus employs barrel-shaped rollers which are suitable for supporting heavy loads and have excellent self-aligning ability and vibration-damping capability. To this end, the barrel-shaped rollers (4) each have a pair of arc-shaped portions (4a, 4b) which gradually decrease in their diameter from a center thereof toward opposite ends thereof. The opposed roller-rolling surfaces (5, 6) are configured such that those regions thereof which correspond to the opposite side arc-shaped portions (4a, 4b) of each roller (4) are composed of arc surfaces (5b, 5b; 6b, 6b) which have a radius of curvature slightly greater than that of the opposite side arc-shaped portions (4a, 4b) of each roller (4) so as to cause differential slips when the rollers (4) are traveling while contacting the opposed roller-rolling surfaces.
