摘要： PROBLEM TO BE SOLVED: To reduce noise and improve operability by reducing the number of times of collision of a ball against a guide member or a rail by controlling the play of the ball when the ball shifts from a linear track to a curved track of a circulation passage.
SOLUTION: An inner guide member 2 of the curved track corresponding to a portion where the ball 3 shifts from the linear track to the curved track is, for example, extended outwardly so as to make the play Dβ of the ball 3 at an inlet of the circulation passage displaced by a phase β from the shift-initiating position smaller than the play Dα of the ball 3 within the circulation passage displaced by a phase α or more from the shift-initiating position, where the ball is under the unloaded condition. Thus, the play of the ball at the outlet and inlet of the circulation passage is decreased so that the number of times of collision of the ball against the guide member or the rail is reduced. Further, by shifting the central axis of the curved track from the center axis of the linear track, or by providing an intermediate inner guide member between a linear track inner guide member and a curved track outer guide member in order to guide the ball at the shifting portion, the play of the ball at the outlet and inlet of the circulation passage can be decreased.

摘要： PROBLEM TO BE SOLVED: To reduce noises and to improve workability by reducing the number of times of a ball colliding against a guide member or a rail by regulating a playing flap of the ball at the time of it transferring from a straight track on to a curved track of a circuit. SOLUTION: The number of times of a ball colliding against each of guide members and a rail by expanding the curved track inside guide member 2 corresponding to a part, for example, to transfer from a straight track on to a curved track outside, reducing a playing flap Db of a ball 3 at a circuit inlet of a phase b from transfer smaller than a playing flap Da of the ball 3 in a circuit to be a no-load state after a phase a from transfer and consequently by reducing a play of the ball at a circuit gateway. Additionally, it is possible toreduce the playing flap of the ball at the circuit gateway even by setting a central axis of the curved track to be slipped out of a central axis of the straight track or by guiding the ball at a transfer part by interposing an intermediate inside guide member between the straight track inside guide member and the curved track outside guide member.

摘要： PROBLEM TO BE SOLVED: To easily and precisely assemble a rolling body and a separator to a bearing body by inserting the rolling body and the separator while adding a returning force to the rolling body and the separator from the direction opposite to the insert port. SOLUTION: When a steel ball 9 is integrated to each circulating passage through an integration port 15a, the height of the steel ball line present on the integration port 15a side reaches about the integration port 15a. At this time, a downward load is added by the dead weight of the steel ball line located on a discharge port 15b side to generate a returning force of the direction opposite to the integrating direction of the steel balls in the integration port-side steel ball line through the steel balls 9 in a U-shaped groove 21. Thereafter, a separator 11 and the steel ball 9 are alternately integrated through the integration port 15a so that the recessed side surface of the separator 11 makes contact with the steel ball 9, and the insertion is continued until the separator 11 is discharged from the discharge port 15b. After the steel balls 9 and the separators 11 are integrated into a bearing body in this way, a temporary shaft is pulled out, and the bearing body is mounted on a rail.
