Who said that the smaller the lead, the greater the load that the screw can bear \x0d\ pure nonsense ~\x0d\ Take Japanese THK as an example, the rated loads of DIK2004-6 screw and DIK2005-6 screw (5.2KN in front and 8.5KN in the back) are obviously large. \x0d\ The reason is simple. The number of steel balls is the same. The smaller the lead, the smaller the steel ball. How does it bear the load \x0d\ The smaller the lead, the slower the walking speed? This is the most direct impact. \ x0d \ x0d \ As for the homogeneous situation, the smaller the lead, the higher the accuracy, and of course the slower the speed. For the ever-changing information market, the use of small leads is still relatively small after all.
