The motion guide device includes a track member in which a rolling member rolling surface is formed along a longitudinal direction thereof, a movable member which is reciprocally movable with a number of rolling members being interposed therebetween and which is provided with a loaded rolling member rolling surface constituting a loaded rolling member rolling path opposing to the rolling member rolling surface and a rolling member return path, and a lid member provided with a pair of direction changing paths for connecting both end portions of the loaded rolling member rolling path and the rolling member return path to thereby constitute an endless circulation path. Flange portions are formed to both end portions of the movable member in the reciprocally moving direction by means of insert molding, and the flange portions are provided with fitting portions formed to end portion sides of the movable member.

Motion guide device

A motion guide device includes a plurality of rolling element guide members provided along the entire length of a rolling element rolling surface so as to guide the unloaded side of a plurality of rolling elements that perform a rolling movement under load between the rolling element rolling surface and a loaded rolling element rolling surface. The rolling element guide member includes a beam member an outer member including a rolling element guide surface for guiding the unloaded side of the rolling elements, and the beam member and the outer member are insert-molded. Such a structure provides the motion guide device including the rolling element guide member that enables low cost manufacturing of a complex shape and capability of secure installation and guidance of the rolling elements with no deflection and can be adapted for use in various types by optionally selecting a connecting means.

There are provided a spherical bearing and a method for manufacturing the same, in which both of a ball bearing section and a ball section made of metal can make light and smooth swinging and rotary motions for a long period of time without biased wear and seize-up of those members even if the solid bodies of them can contact with each other due to a discontinuous oil film under a heavy load. A resin liner that contacts the ball section of the inner member in a sliding relationship is embedded in the ball bearing section, and a resin sliding contact surface provided by the resin liner and the metal sliding surface are adjacent to each other without any gap to form a sliding contact surface at the bearing section.
