特徴とする軌道案内軸受。(1) A pole circulation path in which a large number of poles are disposed so as to be freely transferable between opposing axial pole transfer grooves of a raceway shaft and a saddle member that is crowned by the raceway shaft, and the poles are provided in a retainer. In the orbit guide bearing, the saddle member has a first concave portion having an arcuate cross section and a shallow axial pawl rolling groove on both sides near the opening end, and the retainer has at least one recess having a second recess provided at both ends in the axial direction of the first recess and having a radius slightly larger than the radius of the circular arc of the first recess; The convex surface has a convex surface that fits into the recess of the member, and the convex surface has an elliptical ball circulation path for guiding the pole toward the center of the recess of the saddle □ member, and the pole has a convex surface that fits into the recess of the member. A track guide bearing characterized in that the bearing circulates while being guided toward the center of the bearing.
