Bearing Steel IKO Needle Roller Bearings

IKO Needle Roller Bearings are rotational motion bearings in which a thin needle-shaped roller is incorporated into a rolling element. They have a low cross-section height and high load capacity compared with ball bearings. Being small, needle roller bearings contribute to reducing overall machine size, and are thus widely used in various applications such as automobiles, motorcycles, printing presses, industrial robots and construction equipment.IKO Shell Type Needle Roller BearingsIKO Shell Type Needle Roller Bearings are light weight 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 fixtures for axial positioning are needed. They are ideal for use in mass-produced articles that require economy, and have a wide variety ofIKO Needle Roller CagesIKO Needle Roller Cages for General Usage are bearings which display excellent rotational performance. Needle rollers with extremely small dimensional variations in diameter are incorporated and retained in their specially shaped cages with high rigidity and accuracy, which precisely guide the needle rollers. When combined with shafts and housing bores that are heat treated and accurately ground as raceway surfaces, Needle Roller Cages for General Usage are particularly useful in small spaces. 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 load, and they are used in a wide range of applications. IKO Machined Type Needle Roller BearingsIKO Machined Type Needle Roller Bearings are bearings with a low sectional height and large load ratings. The outer ring has high rigidity and can easily be used even for light alloy housings. These bearings are available in metric series and inch series, both of which have 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 an inner ring. As the type without inner ring uses a shaft as the raceway surface, a compact design is possible.· Caged Needle Roller Bearings· Guide Needle Roller Bearings· Capilube Needle Roller Bearings IKO Combined Type Needle Roller Bearings IKO Combined Type Needle Roller Bearings are combinations of a radial bearing and a thrust bearing. Caged needle roller bearings are used as radial bearings and thrust ball bearings or thrust roller bearings are used as thrust bearings. They are compact and very economical, and can be subjected to radial loads and axial loads simultaneously. They are widely used for machine tools, textile machinery, and industrial machinery.
