- The main body of the clamping ball screw is made of SCM435 equivalent material for RSM, and SUS304 equivalent material for RSU.
- The ball of the clamping screw is made of SUJ2 equivalent material for RSM, and SUS440C equivalent material for RSU.
- The screw is available in eight sizes: M3, M4, M5, M6, M8, M10, M12, or M16.
- The screw can be used with commercially available nuts that are equivalent to JIS6g.
