Abstract
The invention belongs to the technical field of guide pair structures, and discloses a linear guide pair. The linear guide pair comprises a bedplate and a sliding block. At least two cylindrical guiding rails are fixedly arranged on the bedplate. A first bearing and a second bearing which can roll along the guiding rails are arranged on the sliding block, wherein the bearings can rotate. A point contact friction pair is formed among the first bearing, the second bearing, and the guiding rail. An angle formed between a central axis of the first bearing and a central axis of the second bearing is larger than 90 DEG and smaller than 170 DEG.
