Hiwin HG Series Linear Rails

The support body of the ball type linear guide is the ball, and the touch with the slide is point touch (divided into two-point and four point touch types, of course, the more touch points, the better the rigidity, the higher the manufacturing accuracy, and the higher the cost);

Roller type linear guide (interlaced roller guide) is supported by rollers, and the contact with the slide is a line contact. Compared with ball type, the characteristic of ball type is higher rigidity and greater bearing capacity. However, there is a problem that its stroke is limited, unlike most ball type, the stroke can be spliced for a long time (length is not limited).

Relatively speaking, the cost of ball bearing type is lower, the speed can be faster, and the splicing can be longer, which is its advantage; Roller type has greater load-bearing capacity and better rigidity under the same volume.
