ABSTRACT:
A bearing apparatus has a bearing block including balls; two adjacent ball rolling surfaces with the load lines through the balls diverging from or converging toward each other, and unloaded ball passages opposing the ball rolling surfaces; end caps mounted to the opposite ends of the bearing block for forming two endless tracks by providing communication between the ball rolling surfaces and the unloaded ball passages; and a track rail having two ball rolling grooves along which loaded balls roll. The bearing block further includes a separation portion or member and two loaded ball grooves separated by the separation portion or member and having openings which are positioned so that the load lines diverge from or converge toward each other. The width of each of the openings is smaller than the diameter of each of the balls, and the ball rolling surfaces are formed in the loaded ball grooves.
