Stroke Rotary Bushing

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.

The IKO Stroke Rotary Bushing is a linear motion rolling guide with a small diameter and sectional height. It can provide rotary and linear motion in the axial direction simultaneously with rotational motion. It is extremely compact, has high accuracy, and smooth motion with low frictional resistance, making it suitable for various measuring instruments, IC manufacturing devices, precision machines or other small and highly accurate parts.

The IKO Miniature Linear Bushing is an extremely small linear motion rolling guide with a shaft diameter of 3 to 5 mm that performs endless linear motion in the axial direction while making rolling contact with the shaft. Cage, steel balls and stop ring are compactly built in the external cylinder, allowing high feed accuracy to be obtained. Since the steel balls are accurately guided by the cage, stable linear motion can be obtained with small frictional resistance. Compact Design The ultrasmall size allows for compact machine and device design. Wide Variation In addition to the standard type, the highrigidity long type has been serialized and can be selected according to the application. Stainless Steel Stainless steel types are also available, with excellent corrosion resistance and ideal for use in clean rooms, such as in medical equipment, various disc readers and semiconductor manufacturing devices.

The IKO Linear Bushing is a highprecision linear motion rolling guide that performs endless linear motion in the axial direction while making rolling contact with the shaft. Cage, steel balls, and the like are built compactly in the external cylinder. Models are available in abundant sizes and can be selected according to the application. Since the steel balls are accurately guided by the cage, stable linear motion can be obtained with small frictional resistance. Simple Replacement for Rolling Guide With the shaft used as the raceway, guiding parts using conventional bushings can be changed to rolling guides without major design changes. Wide Variation For each dimensional series, standard, adjustable clearance, and open types are available with and without seals, which can be selected according to the application. Stainless Steel Stainless steel types are also available, with excellent corrosion resistance and ideal for use in clean rooms, such as in medical equipment
