The linear motion guide unit has the lubricating means that is easy to be handled, attached to and detached from the track rail by means of supporting a lubricant plate in a holder. The lubricating means has a lubricant plate divided into a pair of lubricant plate components disposed in symmetry with each other, and the holder of a frame surrounding the lubricant plate components to keep steadily the components. The lubricant plate components each have a protrusion which move in sliding contact with raceway grooves of the track rail so as to feed lubricant to the raceway grooves. The lubricant plate components have protrusions fitted into windows in the holder. A pair of the lubricant plate components is supported in such a manner that they are separated by a center wall extending at an upper section of the holder towards the track rail.
A linear motion guide unit comprising a track rail provided at lengthwise side surfaces thereof with first raceway grooves, a sliding element movable relative to the track rail, wherein the sliding element has a casing provided with second raceway grooves in opposition to the first raceway grooves, rolling elements movable along raceways defined between the first and second raceway grooves, end caps secured to the opposing end surfaces of the casing, lubricating means secured on the end caps for feeding lubricant to the raceways defined between the first and second raceway grooves, and end seals secured on the ends of the lubricating means, and further wherein the lubricating means each have a lubricant plate of porous sintered resin immersed with the lubricant, and a holder for supporting the lubricant plate.
