With the development of rolling bearings approximately 110 years ago, rolling contact became the standard method for achieving rolling motion, sparking a great technological revolution. Rolling contact not only conserves kinetic energy but also maintains frictional resistance at low levels, thereby significantly enhancing mechanical performance. However, although the value of similar developments in the field of linear motion might be ten times greater, the technology for achieving linear motion through rolling contact was relatively slow to arrive. Leveraging its unique technological capabilities, THK solved the once-deemed challenging problem of rolling contact linear motion and, in 1972, became the world's first company to develop and commercialize Linear Motion (LM) guides. Using our linear motion systems can rapidly improve the precision and speed of advanced electromechanical machinery while reducing manual labor. THK's LM Rolling Guides enable machine tools and industrial automation machinery to perform ultra-high precision operations and allow semiconductor manufacturing equipment to function within sub-micron environments. Recently, the system has also been applied in liquid crystal production lines, railway passenger cars, assistive vehicles for the disabled, medical equipment, skyscrapers and residences, as well as entertainment facilities. The application scope of LM Rolling Guides has now surpassed all previous limitations.
