Abstract
A linear motion guide unit in which rolling applicators transfer lubricant from a lubricant-containing member to raceway grooves on a track rail to make less sliding-friction resistance to a sliding element. The guide unit has a case accommodating therein the lubricant-containing member, and rolling applicators supported for rotation by a bearing member in the case. The lubricant held in the lubricant-containing member is applied onto the raceway grooves on the track rail through the rolling applicators, the peripheries of which are kept on sliding contact with the lubricant-containing member, thereby lubricating the confronting raceway grooves of the track rail and the sliding element, along which rolling elements run through in the sliding element. The frictional resistance that is encountered when the rolling element run through the track rail is the frictional resistance to rolling motion, which makes less the sliding resistance to the sliding element.
