Abstract
A light-weight miniature linear guide device provides: a guide rail including a first load ball rolling groove formed on an inner surface of the guide rail and extended longitudinally; a slider including a slider body adapted to be fitted in the guide rail, the slider body including a second load ball rolling groove formed on an outer surface of the slider body, and a circulator fitted in the slider body, the circulator having a non-load ball circulating path which is extended longitudinally; a plurality of balls fitted to roll in a space defined by the first and second load ball rolling grooves and the non-load ball circulating path of the circulator. Further, in the miniature linear guide device, the slider body includes a protrusion formed in a longitudinal end portion of the slider body, and a sealing member is secured to the protrusion to sealingly close a gap formed between the inner surface of the guide rail and the slider body. The miniature linear guide device can smoothly be operated even in a dusty atmosphere and prevented from scattering lubricant to lengthen the service life.
