When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1-2, a bridging track includes a guide rail 1 and a plurality of carriage carriages 2 slidably connected to the guide rail 1, wherein the carriage carriages 2 can operate in a chain transmission or belt transmission manner, which is not described in detail in this embodiment. The bottom of the bearing sliding seat 2 is provided with a rolling bearing 3 used for being matched with the guide rail 1, and the embodiment is preferably a floating bearing or a double-row bearing, has stable operation and chipping resistance, and can tolerate a certain range of errors. The side of the rolling bearing 3 is provided with an annular groove 31, the two sides of the guide rail 1 are provided with slide way rings 11 used for being embedded into the annular groove 31, the axial section of the annular groove 31 is of a triangular structure, the cross section of the top of the slide way ring 11 is of an arc structure, so that the top of the slide way ring 11 and the bottom of the annular groove 31 are provided with small spaces, the requirements on the production process can be reduced under the condition of ensuring the use effect, and the resistance of the end part of the bearing slide seat 2 during the operation is reduced.
