THK Linear Motion
THK unique technology made the company worldwide pioneers in the development of the Linear Motion (LM) Guide mechanism. Today, the THK Bearing LM Guide and LM Actuator devices are an indispensable component of mechanical and electronic systems in a wide variety of industries.
THK has developed many other unique mechanical components, including the Ball Spline, Ball Screws and Link Balls.
•LM Guide — linear rolling motion for high-precision, high-rigidity, energy-saving, high-speed machines and long service lives.
•LM Actuator — aluminum base combined with an LM Guide, a standardized top table and drive system.
•LM Guide Actuator — compact actuator with high rigidity and high precision integrated LM Guide with a ball screw. Reduce the number of parts and design man-hours.
•Ball Spline — realize great allowable loads than with linear bushing. Ball spline enables torque transmission while making linear movement.
•LM Roller — high load performance able to make infinite circular motions. Optimal for machines required for high positioning accuracy, repeatability and rigidity.
•THK Application — contact OTP
THK Bearing, The roller linear guide assembly is to place proper steel ball between slide and guide to make slide friction between slide and guide change into rolling with less static friction difference and good follow-up, that is the lagging interval between drive signal and mechanical action is very short, which is beneficial to improving response speed and sensitivity of NC system.
1) The drive power drops substantially equaling to tenth of ordinary machinery;
2) In comparison with V type cross roller guide, the frictional resistance can
decrease by 40 times;
3) Adaptable to high-speed linear movement, its instant speed is higher about 10 times
than sliding guide;
