IKO Shell Type Needle Roller Bearings

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.

Nippon Thompson Co., Ltd. is a bearing manufacturer that launched the technical development of needle roller bearings for the  first time in Japan and is proud of the high  quality level and abundant varieties of its products. Needle roller bearings are bearings for  rotary motion that incorporate needleshaped thin rollers instead of ordinary  bearing balls or rollers. Compared with other rolling bearings, they are small-sized  and lightweight but have a large load capacity. They are widely used with high reliability in the fields of automobiles,  industrial machinery, OA equipment, etc. as  resource-saving type bearings that make the  whole machine
