Longitudinal guide rail for machine tools - has four guide rail sides which fit together and L-shaped roller bearing cages

摘要

The guide rail only uses a small number of components and allows adequate bearing clearance. There are four component parts held together by screws to form a rectangular cross section. The screws fit through the end of one plate into the edge of the next one. The assembly requires at least 8 screws. For high loading roller cages are fitted and these have L-shaped cross section fitting inside the corners of the rectangular support frame with one roller bearing on each leg of the cage. The design can be adapted for use with workpieces with cylindrical cross-section.
