A specialized design combines an external cylinder with a cylindrical raceway and balls that are incorporated in the retainer, making rotary and linear motion in the axial direction possible simultaneously with rotational motion. Super Precision After the raceway surface of the external cylinder and shaft are heat treated, they receive an ultraprecision finish and are set to zero or a slight preload state by incorporating high precision steel balls. This provides extremely high accuracy in both rotary and linear motion. Super Small Size Tiny balls incorporated in a thin external cylinder result in a very small diameter and small sectional height. Since each component is precisely ground and adjusted to ideal preload conditions, extremely smooth and stable operation with low frictional resistance over a long period of time is possible.
