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's Extended Life Specification Machined Type Needle Roller Bearings are treated with a newly developed special heat treatment that enhances the bearing's surface hardness and toughness, and suppresses the generation and growth of damage on the surface. Significant life extension can be achieved under high load or under the condition of lubrication contaminated with foreign substances. In a life comparison test, IKO's special heat treated Extended Life Series products lasted 5 times longer than standard heattreated products.

In IKO Needle Roller Bearings with Separable Cage, the inner ring, outer ring and IKO needle roller cage are combined, but they can be separated easily. This type has a simple structure with high accuracy. In addition, the radial clearance can be freely selected by choosing an assembly combination. Because they use needle roller cages, these bearings have excellent rotational performance, and are best suited for massproduction, high accuracy products such as machine tools, textile machinery, and printing machines.

IKO Roller Bearings are heavy duty bearings with rollers incorporated in a double row. They are nonseparable bearings with a high load rating. They can withstand not only radial loads but axial loads as well, which are supported at the contacts between the shoulders of the inner and outer rings and the end faces of the rollers. They should be used at the fixing side of a shaft. Like needle roller bearings, they are also compact. Roller bearing types include caged, full complement and the type for sheaves, and they can be selected based on the operating conditions. These bearings are used in heavyduty machinery such as construction equipment, and industrial machines.
