Abstract
In a self-lubrication linear guide apparatus including a guide rail, a slider and a plurality of rolling elements, the apparatus further includes a plurality of lubricant-containing polymer spacer balls which are interposed between the rolling elements inside the slider. A lubricant gradually exudes from the lubricant-containing polymer spacer balls as time elapses to be automatically supplied to the rolling elements, so that satisfactory self lubrication can be achieved over a long period of time.
