Axial Rotation: Radial Load Versatile

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 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, 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 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 articles that require economy, and have a wide variety of applications.
