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 this needle roller cage, they utilize the machining accuracy of the way and 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 they are used in a wide range of applications.
The cage is made of synthetic resin, which helps reduce the weight of the device in which the needle roller cage is incorporated. In addition, by optimizing the shape of the cage, the number of needle rollers has increased compared to high carbon steel cages of the same diameter, increasing the load capacity.
