    摘要: To provide a dustproof device for a linear guide rail capable of protecting bolt holes in the linear guide rail from foreign matters such as cutting dust or the like without many tap holes formed in an end face of the linear guide rail. A tension applying means 5 for applying a tension to a band-like cover body 4 includes a tension applying block 13 arranged at an end of a linear guide rail 2, a plurality of pressing plates 14 for pressing the band-like cover body 4 on an upper face of the tension applying block 13, and a pressing plate fixing bolt 15 for fixing the pressing plates 14 on the tension applying block 13. A pair of right and left arm portions 17 each having an engagement convex portion 18 engaging with a rolling element rolling groove 12 in the linear guide rail 2 are provided on the tension applying block 13.

    摘要: A slider slidably mounted on a guide rail has a recess formed in the lower surface of the slider, and a pressure vessel made of elastic material is accommodated in the recess. A friction plate is attached to the lower surface of the pressure vessel to abut against the upper surface of the guide rail. Hydraulic pressure is exerted on the upper surface of the guide rail through the friction plate by the pressure vessel and is adjustable by a pressure control valve so as to vary the frictional resistance between the slider and the guide rail.

    摘要: A linear guide apparatus provides a guide rail extending axially and including a first rolling element groove formed on a side surface; a slider fitted with the guide rail and including a sleeve portion and a second rolling element groove formed on an inner side surface of the sleeve portion, the second rolling element groove of the slider confronting the first rolling element groove of the guide rail; and an under seal attached to a lower portion of the sleeve portion of the slider and projected from the inner side surface of the sleeve portion to slidingly contact with a surface of the guide rail, the under seal including a first projection arranged at an outer edge portion of a width of the under seal, the width being orthogonal to an axial direction of the under seal, the first projection having resiliency for pressing an inner edge portion of the under seal onto the guide rail. The under seal can be attached to the slider correctly without making displacement to ensure a proper seal margin.

    摘要: A linear guide bearing device 1, which serves as the above-mentioned linear guide device, comprises a guide rail 3 and a slider 4. The guide rail 3 includes a plurality of rolling element rolling grooves 5. The slider 4 includes a plurality of load rolling element rolling grooves 8 and a plurality of curved passages 15. The rolling grooves 5 and 8 cooperate together in forming their associated load rolling passages 11 respectively. In an area ranging over each set of the rolling element rolling passage 11 and curved passage 15, there is formed a crowning 20 in a direction where the rolling groove 8 moves away from its associated rolling groove 5. In the end portion of each curved passage 15 on the rolling groove 5 side, there is formed a tongue portion 17. The crowning 20 is structured such that, between the load rolling element 10a that belongs to the rolling elements 10 respectively rolling with a load within their associated rolling element rolling passage 11 and is situated in the end portion of the present rolling element rolling passage 11 and the tongue portion 17 of the curved passage 15, there can be present only one no-load rolling element 10b which rolls with no load.
