Claims
- 1. A linear motion rolling contact bearing assembly, comprising:
- an elongated guide rail extending over a length and having a generally U-shaped cross section, said rail being formed by a steel plate and including a flat wall and a pair of integral side walls;
- a slider member having a generally inverted U-shaped cross section, said slider member being formed by a steel plate and including a flat wall and a pair of integral said walls;
- a plurality of rolling members interposed between said rail and said slider member for allowing relative motion between said rail and said slider member;
- wherein at least one mounting hole is formed in and extends through said flat wall of at least one of said rail and said slider member, said at least one mounting hole being located approximately at the center of said flat wall in the transverse direction which is normal to a direction of relative motion between said rail and said slider member; and
- wherein a pair of slits is formed in said flat wall on opposite sides of said mounting hole to thereby define a mounting area around said mounting hole.
- 2. The assembly of claim 1 wherein said mounting area is projected outwardly from said flat surface.
- 3. The assembly of claim 1 wherein said slits are located symmetrically on opposite sides of said mounting hole in the transverse direction.
- 4. The assembly of claim 3 wherein said slits are arcuate in shape and symmetrical with respect to the center of said mounting hole with a concave side of each of the arcuate slits being directed toward said mounting hole.
- 5. The assembly of claim 3 wherein said slits are straight and parallel to each other.
- 6. The assembly of claim 5 wherein said straight slits extend in parallel with the direction of relative motion between said rail and said slider member.
- 7. The assembly of claim 6 wherein a hole having a diameter larger than the width of the slits is also formed in said flat plate at each end of each of said slits.
- 8. The assembly of claim 1 wherein said steel plate is a thin steel plate.
