A sliding member formed in the axial direction and having a rolling element raceway groove corresponding to the raceway groove of the raceway member formed in the recess thereof, and between the raceway groove of the raceway member and the raceway groove of the sliding member. A rolling bearing for raceway guidance is equipped with a large number of rolling elements that fit together and can roll freely, and has a structure that allows loads to be applied in all directions between a single row of raceway grooves and the rolling elements. The clearance between the raceway groove on the side closer to the bottom of the recess in the sliding member and the rolling element is such that the clearance between the raceway groove on the side closer to the open end of the recess in the sliding member and the rolling element is zero or negative. A rolling bearing for track guidance, characterized in that the clearance is zero or positive when . (2) The length of the raceway groove on the side closer to the bottom of the recess of the sliding member is formed shorter than the length of the raceway groove on the side closer to the open end of the recess of the sliding member. A rolling bearing for track guide as claimed in the first utility model registration.
