THK bearings

THK's creative vision and unique technology make the company a pioneer in the development of linear motion (LM) rails on a global scale. Today, our LM rail equipment has become an indispensable component in mechanical and electronic systems for a variety of industries. THK has also developed many other unique mechanical components, including ball splines, ball screws and connecting rods, which are manufactured by us and made available to customers all over the world.

Our company name "THK" stands for "Toughness", "High Quality" and "Know-how". Our goal is to promote social progress and industry development by following these three principles in technology development and product manufacturing processes. On this website, we will introduce a variety of technologies and products that we have developed.

The moving parts of the machine can be divided into rolling parts, linear motion parts or a combination of both. With the development of rolling bearings about 110 years ago, rolling contact became the standard way to achieve rolling motion. Followed by a great technological revolution. Rolling contact not only saves kinetic energy, but also keeps the frictional resistance at the lowest level, thus greatly improving mechanical performance. However, although the value of such development results in the field of linear motion may be ten times higher than that, the technique of linear motion by rolling contact can be considered to be late.

 

Through its own technical expertise, THK solved the problem of rolling contact linear motion, which was once considered difficult to solve, and became the first company in the world to develop and commercialize a linear motion (LM) guide. The use of our linear motion system can quickly improve the accuracy and speed of advanced mechanical and electrical equipment, and can save manpower. THK's LM Guide allows ultra-high precision machining of machine tools and industrial robots and enables semiconductor manufacturing devices to operate in submicron devices. Recently, the system has also been used in LCD production lines, railway passenger cars, disabled auxiliary vehicles, medical equipment, skyscrapers and homes and recreational facilities. The use of the LM Guide has broken through all previous restrictions.
