Linear Motions
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.
Main Products
Linear Motion Guides
The LM Guide (Linear Motion Guide) is our main product, incorporating a part with a linear rolling motion into practical usage for the first time in the world. It realizes the development of high-precision, high-rigidity, energy-saving, high-speed machines with long service lives.

Ball Screws
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.
