THK bearing

The moving parts of the machine can be divided into rolling elements, linear moving parts or a combination of both. With the development of rolling bearings about 110 years ago, rolling contact became the standard method of achieving rolling motion. A great technological revolution was followed. Rolling contact not only saves kinetic energy, but also keeps the frictional resistance low, thus greatly improving the performance of the machine. However, although the value of such developments in the field of linear motion may be ten times higher than this, the technique of achieving linear motion through rolling contact can be considered too late.

Through its own unique technical strength, THK solved the problem of rolling contact linear motion that was once considered difficult to solve, and in 1972 became the world's company that developed and commercialized linear motion (LM) rails. Use our linear motion system to quickly improve the accuracy and speed of advanced electromechanical instruments and save manpower. THK's LM Guides enable ultra-high precision operation of machine tools and industrial robots, as well as enabling semiconductor manufacturing equipment to operate in submicron devices. Recently, the system has also been applied to liquid crystal production lines, railway passenger cars, disabled assisted vehicles, medical equipment, skyscrapers and residences, and entertainment facilities. The range of use of the LM Guide has broken through all previous restrictions.
