Claims

[Claims for Utility Model Registration] (1) A guide rail made of heat-treated railway rails and extending in the axial direction, and a slider that straddles the guide rail so as to be movable in the axial direction. In the linear motion guide bearing device, an upper surface of the guide rail, a side surface adjacent to the upper surface, and a lower surface adjacent to the side surface are raceway surfaces, and the upper surface raceway is located on the inner surface of the slider at a position opposite to the upper surface raceway surface. A roller circulation linear motion bearing having a roller row that endlessly circulates while rolling on a surface is installed, and an outer ring rolling on the side raceway surface is mounted on the inner surface of the slider at a position opposite to the side raceway surface via rolling elements. A roller bearing fitted to the inner ring is mounted perpendicular to the axis, and a cantilever roller bearing, in which the outer ring rolling on the lower raceway surface is fitted to the stud via rolling elements, is mounted on the lower end of the inner surface of the slider. A linear motion guide bearing device characterized in that the shaft is mounted at an angle. (2) The roller circulating linear bearing is attached to the inner surface of the slider via a self-aligning member.
The linear motion guide bearing device described in (1).
