道案内軸受。The ball of the raceway shaft has an elongated raceway shaft in which two parallel axial ball rolling grooves are formed on each longitudinal side surface, and an axial recess for receiving a part of the raceway shaft. A sliding base in which a ball rolling groove facing the transfer groove is formed on the inner surface of the recess, and a ball rolling groove of the sliding base is fitted between the ball rolling groove of the raceway shaft and the ball rolling groove of the raceway shaft is fitted to allow free rolling. In a track guide bearing comprising a large number of balls, the diameter of the balls on the side closer to the open end of the recess in the slide table is larger than the diameter of the balls on the side closer to the bottom of the recess in the slide table. A track guide bearing characterized by:
