THK's creative ideas and unique technology made the company worldwide pioneers in the development of the Linear Motion (LM) Guide mechanism. Today, our LM Guide devices are an indispensable component of mechanical and electronic systems in a wide variety of industries.
THK has also developed many other unique mechanical components, including the Ball Spline, Ball Screws and Link Balls, which are manufactured by us for supply to customers worldwide.
Who is THK?
Our company name "THK" stands for " Toughness," " High Quality," and " Know-how." We aim to contribute to the improvement of society and development of industry by focusing on these three principles in our technology development and product manufacturing processes. On this site, we will take the opportunity to introduce a variety of technologies and products that we have developed.
LM Guide pioneers
A machine's moving parts can be classified as rolling, linear, or a combination of both. With the development of rolling bearings about 110 years ago, rolling contact became the standard method for accomplishing rolling motion. This brought about a great technological revolution. Rolling contact not only saved motion energy, but also kept frictional resistance to a minimum and thus greatly improved the performance of machinery. However, even though a similar development in the field of linear motion would have been ten times as valuable, linear motion through rolling contact was a long time in coming.
THK solved the problem, previously considered too difficult, of linear motion with rolling contact by applying its unique technological capabilities, and in 1972, it became the first company in the world to develop and commercialize the Linear Motion (LM) Guide. Our linear motion system enabled rapid improvements in the accuracy, speed and labor-saving potential of advanced mechatronic instruments. With THK's LM Guides, machine tools and industrial robots become capable of ultra-precise operations, and semiconductor-manufacturing devices can operate in submicron units. More recently, the system has been applied in liquid crystal manufacturing lines, railway carriages, assistive vehicles, medical equipment, skyscrapers and residences, and amusement devices. The use of LM Guides has truly expanded beyond all prior boundaries.
| Ball Screw The Ball Screw is a high-efficiency feed screw with the ball making a rolling motion between the screw axis and the nut. Compared with a conventional sliding screw, this product has drive torque of one-third or less, making it most suitable for saving drive motor power. | 
| Cross Roller Guide The Cross Roller Guide is a limited stroke linear guide that has precision rollers orthogonalized alternately. This product provides rigid yet supple linear motion and is particularly suitable for linear guidance where high rigidity and supple movement is demanded. | 
| Linear Ball Slide The Linear Ball Slide is a lightweight, compact, limited stroke linear guide unit that operates with very low sliding resistance. It excels in high-speed responsive performance due to its very small frictional factor and low inertia. |

| LM Guide Actuator The LM Guide Actuator is a compact actuator with high rigidity and high precision that has an integrated LM Guide with a ball screw. Reductions in the number of parts and design man-hours can be realised by adopting the LM Guide Actuator. | 
| Slide Pack The Slide Pack is an inexpensive linear guide configured with the press-formed slider and roll-formed rails. It provides lightweight, compact and supple linear motion | |
