<P>PROBLEM TO BE SOLVED: To provide a lubricant supply structure of a ball screw-integrated linear guide bearing, capable of improving flexibility in material selection for a lubricating body. <P>SOLUTION: The lubricant supply structure of a ball screw-integrated linear guide bearing 1 including a linear guide rail 2, a screw shaft 4, a slider 5, a rolling body passage 14 defined by the guide rail 2 and the slider 5, a rolling body circulation path 5d formed inside the slider 5, and a communicating path 6c allowing the rolling body passage 14 to communicate with the rolling body circulation path 5d. An end plate 6 of the slider 5 includes the lubricating body 10 impregnated with lubricant, and the lubricating body 10 is exposed to the communication path 6c to supply the lubricant to a rolling body 5c passing through the communication path 6c for lubricating the rolling body passage 14. <P>COPYRIGHT: (C)2012,JPO&INPIT |
