ABSTRACT:
Disclosed is a roller bearing for linear sliding motion for use in machines such as a machining center. The roller bearing includes a slider having a horizontal portion and a vertical portion depending from one end of the slider, the slider being provided with a pair of loaded grooves. The slider is also provided with a pair of non-loaded portions. A pair of roller guides are attached to the other end of the horizontal portion and to the lower end of the vertical portion, respectively, of the slider and cooperate with the loaded grooves and non-loaded portions to form a pair of endless roller tracks. A track shaft is provided which has roller-contacting surfaces opposing to the roller contacting surfaces formed on the horizontal and vertical portions of the slider. A multiplicity of rollers are disposed so as to be circulated through respective endless roller tracks formed on the horizontal and vertical portions of the slider, thereby to bear the load acting between the roller-contacting surfaces on the slider and corresponding roller-contacting surfaces on the track shaft.
