Self-lubricating linear guide apparatus

A self-lubricating linear guide apparatus in which a fixed amount of lubricant oil is sealed in a lubricant storage chamber, said apparatus comprising a slider having two opposite sides and an end cap, a lubricant storage chamber formed within said slider and two lubricant guide passages formed within said slider with one lubricant guide passage on each of said two opposite sides of said slider with said lubricant storage chamber between said lubricant guide passages, a supply of lubricant oil within said lubricant storage chamber and a fibrous member inserted within said lubricant storage chamber and extending along both of said lubricant guide passages whereby said oil is absorbed by said fibrous member, two rolling element passages each disposed at one of said opposite sides of said slider within said slider and adjacent to one of said lubricant guide passages, a plurality of rolling elements within each of said rolling element passages, and said fibrous member protruding into each of said rolling element passages for contact by said rolling elements to thereby lubricate said rolling elements with said lubricating oil, an oil infusion aperture within said slider for replenishing said lubricant oil and a sealing washer interposed between said slider and said end cap to prevent leakage of lubricant oil therefrom.
