THK Linear Rail Block SR 25
THK's innovative ideas and unique technology have made the company a pioneer in developing linear motion (LM) guideways worldwide. Today, our LM guideway equipment has become an indispensable component of machinery and electronic systems in various industries. THK has also developed many other unique mechanical components, including ball splines, ball screw and connecting rod balls, which we provide to customers around the world.
THK solved the problem of rolling contact linear motion that was once considered difficult to solve, and in
1972 became the first company in the world to develop and commercialize 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
Recently, the system has also been applied to liquid crystal production lines, railway passenger cars,
disabled assisted vehicles, medical equipment, skyscrapers and residences, and recreational facilities.
The range of use of the LM Guide has broken through all previous restrictions.
THK miniaturized, heavy-duty SR series:
Product features: THK SR series is suitable for horizontal guides because of the low-profile design of the
miniaturized design with a steel ball contact structure with a high load-bearing capacity in the radial
