For the JUP type guide rail, the LM Guide series achieves the maximum load capacity by providing six rolling grooves. The "JUP780" with a slider length of 740 mm and a slide rail width of 230 mm has a basic static load rating (Co) of 6540 kN in the radial direction. Previously, the series had a maximum basic static load rating of 1300kN.
Further, by adopting a structure in which four rolling grooves are formed at a contact angle of 90 with the groove on the slide rail, it is possible to withstand a large load in the radial direction. The price is 1.5 million to 2 million yen.
THK is on the market for rolling linear guides for very large machine tools
THK has launched the "LM Guide JUP" series of high-load capacity rolling linear guides for ultra-large machine tools such as five-face machining machines and portal milling machines. In general, the above-mentioned super-large machine tools use sliding guide rails, but by adopting this The rolling JOP-type guide rails are not only expected to improve the speed, accuracy and maintainability of the machine tool, but also shorten the assembly time.
