成したことを特徴とするリニアガイド装置。 At least three rows of ball rolling grooves are formed on both sides of a guide rail that extends long in the axial direction, and opposing ball rolling grooves are formed on both sleeves of a slider that is movably straddled over the guide rail. A ball rolling groove and a ball circulation path parallel to the ball circulation path are provided, and a large number of balls are provided which circulate as the slider moves through the ball circulation path. Some have two-point contact between the groove surfaces of the ball rolling groove on the opposing guide rail side and the ball rolling groove on the slider side, and those in the ball rolling groove on the intermediate stage are in contact with the ball rolling groove on the opposing guide rail side. A linear guide device characterized in that the ball rolling groove on the slider side is configured to make contact at four points between the groove surfaces of the ball rolling groove on the slider side.
