Abstract
A linear guide apparatus is provided with two (upper and lower) tracks of rolling element race tracks formed on a guide rail and of rolling element race tracks formed on a slider main body so as to oppose the rolling element race tracks on the respective sides, i.e., four tracks of race tracks in total. A recess is provided below the lower rolling element race track on the slider main body and the end cap fixed to an end face of the slider main body is provided with a projection that engages with the recess so as to determine a position of the end cap.
Claims10
A linear guide apparatus comprising:
- a guide rail having a plurality of rolling element race tracks provided on each of side faces of said guide rail;
- and
- a slider having leg portions disposed widthwise over both sides of said guide rail and a horizontal portion connecting the leg portions, said slider including a slider main body and a pair of end caps respectively fixed to end faces of the slider main body, the slider main body having a plurality of rolling element race tracks, which are provided on an inner face of the respective leg portions of the slider main body so that both of the rolling element race tracks of said guide rail and the slider main body form rolling passages, and a plurality of return passages axially penetrating through the slider main body, the end caps each having a plurality of direction reversal paths communicating with the respective rolling passages and return passages of the slider main body,
- wherein the slider main body has first recesses each of which provided below the rolling element race track close to an end portion of each of the leg portions, and each of the end caps has first projections each of which engages with the first recess so as to determine a position of the end cap, and
- wherein each of the end caps has second projections each having a face to be in contact with the inner face at a base end portion of each of the leg portions of the slider main body.
