Abstract
A miniature linear guide provides a guide rail and a slider that is fitted inside the guide rail in an axially slidable manner via a number of balls and that is an integral assembly of a slider body and a circulator that is fitted in the concave portion of the slider body and which has internal, axially extending unloaded ball circulating paths. Since a lubricant-containing polymer member is provided between the unloaded ball circulating paths in such a way that it contacts the balls, the lubricant oozes slowly out of the polymer member to be supplied automatically to the surfaces of the balls over an extended period so as to assure long life for the miniature linear guide.
