案内軸受。[Scope of Claim for Utility Model Registration] 1. A raceway shaft having U-shaped grooves formed on both sides of the side surface having two mutually parallel axial ball transfer grooves on both sides;
a slide table having a groove for receiving the raceway shaft and a ball rolling groove corresponding to the ball transfer groove of the raceway shaft formed on the inner surface of the groove; In a track guide bearing in which a large number of balls are disposed so as to be freely transferable between a ball transfer groove on a raceway shaft, a contact line of the balls that fit into two ball rolling grooves on one side of the raceway is connected to the track. A track guide bearing characterized in that the shafts cross each other at a substantially right angle in the cross section outside the track axis. 2. The groove of the slide table has a trapezoidal shape that expands outward, and the side surface of the track axis has an inclined surface corresponding to the trapezoidal groove of the slide table, and the U-shaped groove is formed on this inclined surface. The track guide bearing according to claim 1, wherein a groove in the shape of a shape is formed.
