THK Linear Bush Metal Retainer Type with Seal

Linear bushings LM type is used in combination with a cylindrical LM shaft and is a linear motion system that moves in an infinite linear motion. Although the load ball and the LM shaft are in point contact, the allowable load is small, but linear movement is made with minimum frictional resistance, and highly accurate and light motion can be obtained. The outer cylinder uses high carbon chromium bearing steel, and after heat treatment, contents and outer diameter are ground. Dimensional tolerances of each part of the linear bush are standardized and therefore compatible. Since the LM shaft can be machined with cylindrical grinding that is easy to process, high fitting clearance can be obtained. Since the retainer guiding the ball row is integrally Formed, it guides accurately in the direction of travel of the ball, and stable running accuracy can be obtained. Because the retainer integrally molded with synthetic resin is used, the sound during exercise is small and excellent in lubricity. The outer cylinder and the flange are unitary, it can be fixed directly to the housing, and it is easy to install. A special synthetic rubber seal is incorporated on both sides to prevent invasion of foreign matter and to suppress leakage of grease._x000D_
