Caged Needle Roller bearings that 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, precisely guiding the needle rollers, making them particularly useful for general-purpose use 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.
