  The moving parts of the machine can be divided into rolling parts, linear parts or combination parts. With the development of rolling bearings about 110 years ago, rolling contact has become a standard method to achieve rolling motion. A great technological revolution ensued. Rolling contact not only saves kinetic energy, but also keeps friction resistance at a low level, so it can greatly improve the mechanical performance. However, although the value of such developments in the field of linear motion may be ten times higher, the technology of realizing linear motion through rolling contact is still a long way off.

  Through its unique technical strength, THK solved the problem of rolling contact linear motion which was once considered difficult to solve. In 1972, it became a company in the world that developed and commercialized linear motion (LM) guideways. Using our linear motion system, we can improve the precision and speed of advanced mechanical and electrical equipment quickly, and save manpower investment. THK's LM rolling guide enables ultra-high precision operation of machine tools and industrial automation machines, and enables semiconductor manufacturing devices to operate in sub-micro devices. Recently, the system has also been used in LCD production lines, railway passenger cars, auxiliary vehicles for the disabled, medical equipment, skyscrapers and residences, as well as entertainment facilities. LM rolling guide has broken through all previous restrictions.
