THK Linear Ball Slide is a highly corrosion resistant slide unit that has an extremely low friction coefficient because stainless steel balls roll on four stainless steel needle roller raceways that are hardened and ground. Its components are all made of stainless steel, which is highly corrosion resistant. Furthermore, since its inertia is small, the slide system is highly responsive to high speed. By simply securing the Linear Ball Slide on the mounting surface, the user can easily achieve a linear guide mechanism.
