ABSTRACT The invention relates to a ball-bearing bushing for unlimited linear movements along a shaft, the said bushing consisting of balls and steel needles disposed within a single sleeve made of a synthetic material, formed in one operation. Formed in the sleeve are ball tracks consisting of two straight sections united by two curved sections. Balls circulating in the tracks are prevented from falling out by the steel needles and by the special configuration of the tracks. The said steel needles are snapped into mountings in the sleeve and also constitute guides for the rows of load-carrying balls in the operating areas. During their entire circulation balls are in contact with the steel needles associated with one set of balls. Ball-bearing bushings of this type are of extremely economical design, since they comprise only three basic elements: the sleeve, the balls, and the steel needles, and these elements can be assembled without any additional operations, for example welding or mechani- cal reshaping, and without any additional parts such as lateral discs, circum- ferential clips, or other special aids.
