Abstract
A linear motion guide unit is disclosed in which a lubricant-impregnated plate is mounted on any one side thereof with a backing plate and accommodated in a cartridge. The lubricant-impregnated plate is less subject to deformation or distortion, thus continuing to keep precisely the sliding relation with the raceway grooves on the track rail. Lubricating means are arranged on end caps of the slider, one on each end cap. The lubricating means is composed of a lubricant-impregnated plate of sintered resinous component, a backing plate high in stiffness attached to the lubricant-impregnated plate into a composite plate, and a cartridge accommodating therein the composite plate. The backing plate and cartridge, in combination, sustain squeezing load caused when the lubricating means is fastened to the slider. Thus, the lubricant-impregnated plate is free from the squeezing load, keeping precise sliding-contact relation with the raceway grooves on the track rail.
