[Key company in mechatronics]
The moving parts of machinery can be classified as rolling, linear, or a combination of both. With the development of rolling bearings about 110 years ago, rolling contact of rolling motion was achieved. This brought about a great technological revolution. Rolling contact not only saved motive energy, but also kept frictional resistance to the minimum and thus greatly improved the performance of machinery. However, even though the merits of rolling contact of linear motion are more than ten times those of rolling motion, rolling contact of linear motion was a long time in coming.

In 1972, applying its unique technological skills, THK developed a method of linear motion with rolling contact. Thus it became the world's first company to develop and commercialize the Linear Motion (LM) Guide. Our linear motion system, by leading to rapid and epoch-making improvements in the accuracy and speed of advanced mechatronic instruments such as machine tools, industrial robots, and semiconductor- manufacturing devices, has made possible ultra-precise operations, to submicron standards. Recently, the system has been applied in liquid crystal manufacturing lines, pendulum-type railway carriages, automobiles, medical equipment, amusement instruments, and earthquake- proofing devices for structures such as skyscrapers. Its use has expanded beyond boundaries.
[Moving to the world market: "Global-10 21"]
Our company is currently working under a program and outlook called "Global-10 21." Its purpose is to spur us to grow into a top-ten global machine element manufacturer by the 21st century. Though this target may seem overambitious, we believe we can reach it, given the potential of the Japanese market and the virtually infinite capacity of the world market. THK has taken steps to ensure the success of this enterprise. In the expectation that we will make our full-scale debut in the world market very soon, we have expanded overseas distribution bases, increased our nvestments in equipment for domestic plants, and raised our production capacity. We are now pouring effort into promoting technical and business partnerships with university and corporate laboratories to strengthen programs for developing new technology and products.

[THK - A technologically creative company]
Since its inception, THK has anticipated the blossoming of electromechanical engineering. As a result, it actively participated in research into innovative advanced technology. This is best exemplified by linear motion systems. THK's many patents in Japan and other countries are evidence of its pioneering spirit, and the basis for its reputation as a worldwide leader in electromechanical innovation and creativity.

At THK, we will never feel that we have reached the top; our goals have no boundaries, we will continue to search for new horizons. Our development philosophy is, "Be faithful to basic principles; be bold and innovative in applying them." The field of application is boundless for THK products, which reflect both an uncompromising design ideology and a basic policy geared for the world market. THK products transcend preconceived ideas, and will continue to lead the precision machinery industry. Strategic groups based on these ideas have been formed in 2001 and 2002, and they are expected to play an active part from now on.
