IKO Spherical Bushings are compact selfaligning spherical bushings with inner and outer rings in contact with the sphere, which can support a large radial load and a bidirectional axial load at the same time. There are many models of Spherical Bushings, but they are basically divided into steelonsteel types and maintenancefree types according to the kind of sliding surfaces. Steelonsteel Spherical Bushings have inner and outer rings of highcarbon chromium bearing steel, of which sliding surfaces are phosphatetreated and then drycoated with molybdenum disulfide (MoS2). They can, therefore, operate with low torque, and have excellent wear resistance and large load capacity. They are especially suitable for applications where there are alternate loads and shock loads. They have wide applications mainly in industrial and construction machinery. Maintenancefree Spherical Bushings consist of an outer ring which has a special PTFE liner reinforced

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.

The cage is made of synthetic resin, which helps reduce the weight of the device in which the needle roller cage is incorporated. In addition, by optimizing the shape of the cage, the number of needle rollers has increased compared to high carbon steel cages of the same diameter, increasing the load capacity.

IKO Needle Roller Cages for Engine Connecting Rods are bearings for use in engine connecting rods. These bearings have superior performance proven in high performance engines of racing motor cycles, and are widely used in small motor vehicles, motor cycles, outboard marines, snow mobiles, highspeed compressors, etc. and also in generalpurpose engines. Bearings for engine connecting rods are used under extremely severe and complex operating conditions such as heavy shock loads, high speeds, high temperatures and stringent lubrication. Needle Roller Cages for Engine Connecting Rods are lightweight, and have high load ratings and high rigidity as well as superior wear resistance to withstand severe conditions.
