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.
