Linear motion systems & precision components
THK is a global pioneer in linear motion technology — best known for the LM Guide (linear motion guide), along with ball screws, ball splines, actuators, cross-roller rings and related precision components. THK linear-motion systems are a default specification in machine tools, semiconductor and electronics equipment, robotics and automation worldwide.
THK is a Japanese brand. ProSource MRO supplies genuine THK products through established Korean distribution channels — so buyers abroad get authentic parts, correct model matching and consolidated export from Korea, without managing suppliers across multiple countries.
