LINEAR BALL BEARING
The invention relates to a linear ball bearing comprising a guiding carriage (2) that is guided on a guide rail (1) in a longitudinally displaceable manner and is mounted on rolling bearings on longitudinal sides of the guide rail (1) by means of balls (3) that are arranged on each longitudinal side in at least two parallel rows (4, 5) running along continuous ball channels (6). Each ball (3) pertaining to one row (5) of balls is held all-round in separator pockets (8) of a common separator part (7), with an adjacent ball (3) pertaining to the other row (4) of balls. A separator part (7) comprises exactly two pockets (8) for a ball (3) from both rows (4, 5). The two ends of each separator part (7) are provided with end faces (9) which are convex in the moving direction of the balls (3), in order to be brought into contact with the end faces (9) of adjacent separator parts (7), said end faces (9) extending essentially up to the sides (10) of the separator parts.
