用ボールベアリング。 A pair of raceway surfaces each having a concave cross section perpendicular to the axial direction and having a radius of curvature slightly larger than the ball diameter are formed on both opposing sides of the bearing and the way, and the upper and lower raceway surfaces of the bearing and the way are formed. In a linear motion ball bearing with a difference in the distance between the centers of curvature of the bearing, the distance between the centers of curvature of the upper and lower raceway surfaces of the bearing is set to be larger or smaller than the reference value of zero clearance when the ball is sandwiched. A ball bearing for linear operation that is characterized by applying preload.
