As a preferable technical scheme of the utility model, the two sides of the guide rail are provided with the arc grooves which are contacted with the steel balls, and compared with point contact, the guide rail has the advantages of high bearing capacity and good rigidity.

As a preferable technical scheme of the utility model, the sliding block is in sliding connection with the arc groove of the guide rail through the steel balls, and the steel balls can roll and circulate infinitely between the sliding block and the guide rail, so that the load platform can move linearly along the guide rail easily with high precision, the friction coefficient is reduced to one fiftieth of that of the conventional sliding guide, and very high positioning precision can be achieved easily.

As a preferable technical scheme of the utility model, the guide rail is arranged in an I-shaped structure.

The utility model adopts the structure to obtain the beneficial effects as follows: according to the hollowed-out light linear guide rail provided by the utility model, the material removal and the structural optimization are carried out on the guide rail through the arrangement of a plurality of groups of hollowed-out holes on the guide rail, so that the total weight of the guide rail is reduced; the steel balls roll and circulate infinitely between the sliding blocks and the guide rail, so that the load platform can move linearly along the guide rail easily with high precision, the friction coefficient is reduced to one fiftieth of that of the conventional sliding guide, and high positioning precision can be achieved easily.
