Features

• The combination of an outer cylinder with a cylindrical raceway surface and a steel ball built into the cage enables axial reciprocating linear motion simultaneously with rotational motion.
• Since a steel ball of an extremely small size is incorporated into the thin outer cylinder, an extremely small section height is realized with a small diameter.
• High-precision steel balls are incorporated into the super-finished outer cylinder and shaft to adjust to zero or slight preload conditions, resulting in high-precision rotation and reciprocating linear motion.
• Each component is precisely finished and adjusted to an ideal preload condition, resulting in extremely smooth and stable motion with low rolling friction resistance over a long period of time.
