摘要： PROBLEM TO BE SOLVED: To provide a linear guide rail and a work method therefor for reducing a cost at work time and securing required accuracy by applying a rolling technique to a linear groove. SOLUTION: When machining this linear guide rail having a track groove 2 on a side surface, the track groove 2 is rollingly worked on a rail raw material W by using a rotary die having in a circumferential part a projecting work part T adjusted to a shape of the track groove 2. Since the track groove can be worked with high accuracy in a single process, work time is shortened more than a conventional work method by drawing → cutting → grinding work to reduce a work cost.

摘要： PROBLEM TO BE SOLVED: To provide a linear motion guide device capable of suppressing the dynamic friction force when a guide member is moved and suppressing change in the dynamic friction force. SOLUTION: A linear motion guide bearing device 1 as a linear motion guide device is equipped with a guide rail 3 and a slider 4, wherein the guide rail 3 is furnished with a rolling groove 5 for rolling elements, while the slider 4 is furnished with a loaded element rolling groove 8 and a curved path 15. The two rolling grooves 5 and 8 constitute a load rolling path 11. A crowning 20 is formed in the direction that the rolling groove 8 separates off from the rolling groove 5 in the range over the rolling path 11 and curved path 15. A tongue 17 is provided at the end of curved path 15 on the side with rolling groove 5. The crowning 20 is configured so that there is only one 10b of the rolling elements 10 moving in the loaded condition within the rolling path 11, i.e., one non-load rolling element 10b moving in the unloaded condition exists between the loaded rolling element 10a positioned at the end of the rolling path 11 and the tongue 17.
