There are many types of silk rods, many of them, sometimes with the manufacturer's abbreviation, serial number, etc., so it is impossible to say
The semiconductor plug-in unit, small robot, and so on require the micro guide ball screw pair to meet the high speed drive requirement. As mechanical products to develop in the direction of high speed, high efficiency, automation, industrial robot, CNC forging machinery, processing center, and mechanical and electrical integration of automatic machinery, such as increasing the feed drive speed
The expansion of the use of the ball screw pair using field expands unceasingly, more and more to the requirement of ball screw pair, the common specifications of the ball screw pair has far cannot satisfy the use requirement, such as aerospace field, small precision testing device, electronic instrument and semiconductor device basically need d0 nominal diameter 12 mm or less, lead Ph = 0.5 ~ 2.5 mm mini ball screw pair. Japan's NSK company has developed the world's smallest lead micro-ball screw with a diameter d0 = 4mm and the lead Ph = 0.5 mm. 15 straight screw? 1510 ball screw and so on, the manilus is pretty good
