ABSTRACT:
A ball circulation unit in which a cage guiding balls consists of inner segments and head pieces which are axially connected to each other by centering bars so as to form one unit held in the basic member. The centering bars may be fixed in the head pieces, for example, and the centering bars increase the stiffness of the cage, permit it to be manufactured from plastics and achieve accurate centering of the cage parts relative to each other, thereby ensuring undisturbed circulation of the balls in the ball rows.
