Linear ball bearing
 A new ball circulating system for a linear ball bearing that greatly simplifies the manufacturing process of the ball bearing. The linear ball bearing includes an outer sleeve, a ball retainer, several ball tracks and two snap rings. Each ball track includes a linear loaded ball groove and a linear unloaded ball groove, and two semi-circular ball turning grooves which allow the steel balls to turn 180 degrees between the two linear ball grooves. The turning grooves include two-stage depth variations to simplify the geometry of the inner surface of the outer sleeve, to provide better manufacturability, and to increase the bearing's overall strength and longevity.
