THK SHS45-570L Linear Guide Rail

The THK SHS45-570L Linear Guide Rail delivers precise, high-rigidity linear motion with a 45 mm profile and a 570 mm overall length, ideal for CNC machines and automation equipment. As part of THK’s SHS Caged Ball LM Guide GK Series, it uses a four-way equal-load design and caged-ball technology for smooth, low-friction travel, supported by hardened bearing steel (58–64 HRC) and grease- or oil-lubricated operation. Key specs include rail size 45 mm, width 45 mm, height 37.5 mm, standard hole pitch 105 mm, end distance 22.5 mm, mounting hole size 14×20×17 mm, and M14 screws with bolt-mounted-from-above mounting; compatible THK guide blocks are SHS45C, SHS45LC, SHS45R, SHS45V, and SHS45LR, with maximum standard rail length 3090 mm. Common applications span factory automation systems, CNC machine tools, electronics manufacturing equipment, robotic positioning systems, material handling machinery, medical equipment, and automated inspection and assembly machines; maintenance teams and system integrators use the SHS45-570L for repairs, retrofits, upgrades, and replacement of worn or damaged rails.
