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.

IKO Shell Type Needle Roller Bearings are lightweight bearings with large load ratings. They employ a shell type outer ring made from a thin specialsteel plate which is accurately drawn, carburized and quenched, thus providing the lowest sectional height among the Needle Roller Bearings. There are two types of bearings available in this series; the caged type and the full complement type. The appropriate type can be selected according to the operating conditions. The caged type has a structure in which the needle rollers are accurately guided by the cage and thrust rings. It is useful for applications at highspeed rotation. The full complement type needle roller bearing, on the other hand, is suitable for heavyload applications at lowspeed rotation. Since these bearings are pressfitted into the housing, no axial positioning fixtures are required. They are ideal for use in massproduced articles that require economy, and have a wide variety of applications.

IKO Combined Type Needle Roller Bearings are combinations of a radial bearing and a thrust bearing. Caged Needle Roller Bearings are used as radial bearings and thrust ball bearings or thrust roller bearings are used as thrust bearings. They are compact and very economical, and can be subjected to radial loads and axial loads simultaneously. They are widely used for machine tools, textile machinery, and industrial machinery.

Since the stud is eccentric, it can be aligned by rotation, and can be easily adjusted so that the load distribution on the outer surface of the outer ring is uniform. These are eccentric cam followers with a onepiece stud that can be mounted in the same mounting holes as those for Standard Type Cam Followers. The eccentricity is 0.25 mm to 0.6 mm.
