  • Publication number: 20230258232
    Abstract: A guide device includes a track member and a moving member engaged with the track member with a plurality of rolling elements interposed therebetween. A lubricating path is formed in the moving member for supplying lubricant to a circulation path for the rolling elements. The lubricating path has a common path including an inlet portion that serves as a supply port for the lubricant, a first path through which grease flows, and a second path through which lubricating oil flows. A cross-sectional area of the second path is smaller than a cross-sectional area of the first path, and in the common path, a second communication portion of the second path is located closer to the inlet portion than a first communication portion of the first path. Further, the guide device includes a plug member for blocking the inlet portion of the common path, the plug member being removable and able to be moved within the common path.

  • Publication number: 20230182247
    Abstract: A guide apparatus includes a track member, a movable member having a first rolling surface that forms a load rolling passage together with a rolling surface of the track member, and a damper provided on a first surface. The first surface is at least a portion of the surface of the movable member opposed to the track member excluding the first rolling surface. The damper includes a plate member disposed in such a way as to cover the first area and a reservoir space formed between one surface of the plate member and the first area. The reservoir space contains a damping medium and allows the plate member to displace relative to the first area. The damper is provided on the movable member in such a way that the other surface of the plate member slides on at least a portion of the surface of the track member opposed to the movable member.
