グユニット。(1) A bearing block material is formed by pultrusion forming a substantially U-shaped no-load ball groove on the top surface of the main body, a depression with a substantially trapezoidal cross section in the center of the bottom of the main body, and skirts on the left and right sides sandwiching the depression. Four load ball grooves having a radius of curvature that is approximately the same as the ball diameter are formed in the axial direction on the trapezoidal concave top wall and the lower hook-shaped receiving portion of the inclined wall. A bearing block body in which a no-load ball groove is formed on the outer periphery of the hook-shaped receiving part parallel to the loaded ball groove of the lower hook-shaped receiving part, and a cover is attached to the abbreviated-shaped non-load ball groove of the bearing block body. A no-load ball guide is formed by this, and then the side cover with a retainer attached to both end faces of the bearing block body has a U-shaped groove for ball direction conversion that corresponds to the loaded ball groove and the no-load ball groove of the bearing block body. The side cover with the retainer has a diameter approximately equal to the ball diameter.
In addition, a load ball guide from which the balls do not fall is formed in the axial direction, a notch is formed in a part of the horizontal member of the cage in which the load ball guide is formed, and a trapezoidal cross-sectional shape that fits into the notch is formed. A side plate is fixed to the top wall of the bearing block main body via a plate, and is further attached to the lower hook-shaped receiving portion of the inclined wall.The left and right receivers receive members and a no-load ball guide is formed, so that a large number of balls can be attached to the bearing. A bearing formed by filling a block body and a side cover with a retainer, and a load ball groove having a radius of curvature approximately the same as the ball diameter corresponding to the load ball groove of the bearing block body on the left and right protrusions. A linear ball bearing unit characterized in that tracks having a substantially X-shaped cross section are respectively formed on the upper wall surface and the lower inclined surface of the bearing block, and push bolts are installed at required locations on the bearing block body. .
