Linear guide with lubrication device

A linear guide with lubrication device, comprising:

• an elongate rail, which comprises an elongated strip like structure extending in a given direction, the direction being defined as an axial direction, the elongate rail being provided, on two opposite sides of the axial direction, with rolling grooves respectively;
• a slide module, which is slidably mounted on the elongate rail and comprises a slide block and two recirculation members, the slide block being provided with rolling channels respectively corresponding to the rolling grooves such that each of the rolling grooves and the corresponding one of the rolling channels collectively define a loading path, the slide block being further provided with a plurality of recirculation holes each extending through two end faces thereof in the axial direction, the two recirculation members being respectively mounted to the two end faces of the slide block, the two recirculation members being each provided with a plurality of recirculation passages each having two ends respectively connected to and communicating with the loading paths and the recirculation holes such that the loading paths each combining the recirculation holes and the recirculation passages to form a circulation path and the circulation path receives a plurality of rolling bodies disposed therein;
• wherein at least one of the recirculation members comprises a lubricant reservoir and fixing through holes formed therein such that the lubricant reservoir, the recirculation passages, and the fixing through holes are in communication with each other, the lubricant reservoir receiving lubricant filled therein;
• an application member, which is arranged in each of the fixing through holes;
• a transferring member, which is set on and covers the application member, the transferring member absorbing and transferring the lubricant to the application member, such that the rolling bodies, when moving through the recirculation passages, are allowed to contact the application members;
• wherein the recirculation members each comprise a positioning lid, the positioning lid being set on and covering the lubricant reservoir and holding and thus fixing the transferring member in position.
