Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
As shown in fig. 1, 3 and 4, a wear-resistant linear guide comprises a sliding base 3 and a guide base 5:
a driving component 1 is arranged on the guide rail seat 5, and the driving component 1 drives the sliding seat 3 to reciprocate along the length direction of the guide rail seat 5;
a connecting pipe 35 is arranged on the inner wall of the vertical end of the sliding seat 3, and the outer wall of the connecting pipe 35 is rotatably connected with a ball 34;
the guide rail seat 5 is provided with a rolling groove 6 matched with the rolling ball 34;
