1、Achieve the accuracy of a 3D printer or the power of a scissors jack, the pitch of the guide screw refers to the distance from one thread to another 2、The 8mm guide screw have 4 threads with a pitch of 2mm. So that each time the guide screw rotates, the linear stroke of the guide screw nut is 8mm 3、Come with 8mm diameter, making the product compatible with many components, such as 8mm sleepers and 8mm thrust bearings 4、Adopt stainless steel material with corrosion resistance, heat resistance, high temperature and ultra‑low temperature resistance, good comprehensive mechanical properties and high strength 5、An excellent mechanism to convert rotation into linear motion, used for accessories in the field of robotics
