ABSTRACT:
This invention provides a linear motion guide unit provided with lubricating plates capable of being applied to existing linear motion guide units without changing the basic specifications thereof, and capable of being fixed to and removed from a casing easily. The lubricating plates are disposed between spacers fixed to end surfaces of end caps and end seals, and fixed to a casing, the lubricating plates slidingly contacting at least the raceway grooves in a track rail and being moved relatively to the track rail. The lubricating plates comprise sintered resin members having lubricating oil-impregnated porous structures. The sintered resin members are made by filling a predetermined metal mold with fine particles of a synthetic resin, and thermally molding the same particles.
