Axial Rotation: Radial Load High-Speed Rotation

IKO Shell Type Needle Roller Bearings are lightweight bearings with large load ratings. They employ a shell type outer ring made from a thin, special steel plate which is accurately drawn, carburized and quenched, providing the lowest sectional height among needle roller bearings. There are two types of bearings available in this series, caged type and full complement type. The appropriate type can be selected according to 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 with high-speed rotation. The full complement type needle roller bearing, on the other hand, is suitable for heavy-load applications at low-speed rotation. Since these bearings are press-fitted into the housing, no axial positioning fixtures are required. They are ideal for use in mass-produced products that require economy, and can be used in a wide variety of applications.

IKO Needle Roller Cages for General Usage are bearings that provide excellent rotational performance. Their specially shaped cages, with high rigidity and accuracy, precisely guide the needle rollers. Since needle rollers with extremely small dimensional variations in diameter are incorporated and retained in the needle roller cage, they utilize the machining accuracy of the way. They are useful in small spaces when combined with shafts and housing bores that are heat treated and accurately ground as raceway surfaces. In addition, since they are lightweight and have high rigidity, as well as a large lubricant holding capacity, they can withstand severe operating conditions such as high speed rotation and shock loads, and can be used in a wide range of applications.

IKO Machined Type Needle Roller Bearings are bearings with a low cross sectional height and large load ratings. The outer ring has stable high rigidity and can be easily used even for light alloy housings. These bearings are available in metric series and inch series, models for both of which include the caged type and the full complement type. It is therefore possible to select a suitable bearing for use under various conditions such as heavy loads and high-speed or low-speed rotations. In addition, there are bearings with and without inner ring. As the type without inner ring uses a shaft as the raceway surface, a compact design is possible.

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