The method for manufacturing a linear motion guide device includes a step of forming a long member () having a pair of side wall parts () and a bottom wall part (), a step of attaching a track body () to the pair of side wall parts () of the long member (), and a step of cutting away a base member () to which the track body () is attached by cutting the long member () together with the track body () into a desired length.

Linear motion guide device and method for manufacturing linear motion guide device

A motion guide device is formed of: a track member including a base portion extending along a longitudinal direction, and a pair of wall portions erected from both edges of the base portion in a width direction, and having rolling element rolling grooves formed along a longitudinal direction; and a moving member which is assembled in a movable manner along the longitudinal direction between the wall portions, and to which a pair of guide members are assembled, load rolling element rolling grooves which correspond to the rolling element rolling grooves being formed in the guide members, wherein at least either one of the guide members is equipped with a biasing member on a surface of the guide member on a side opposite to a surface of the guide member on which the load rolling element rolling groove is formed.

Motion guide device

An actuator includes a track member provided with a base extending along a longitudinal direction and a pair of walls erected from opposite ends of the base in a width direction, with rolling-element rolling grooves formed along the longitudinal direction; and a moving member assembled movably along the longitudinal direction between the walls, with respective load rolling-element rolling grooves corresponding to the rolling-element rolling grooves being formed in the moving members; and a screw shaft passed through a through-hole formed in the moving member, with a screw rolling-element rolling groove formed in the screw shaft, the screw rolling-element rolling groove being spiral in shape, wherein the moving member has the nut member attached to the through-hole, with the screw load rolling-element rolling groove corresponding to the screw rolling-element rolling groove formed in the nut, the nut member is assembled via a flange member which includes a lubricant supply device.
