These bearings consist of an IKO NEEDLE ROLLER CAGE combined with the inner and outer rings, and as they are separable, handling is simple. Also, as oil lubrication is easy, they are suited to high rotational speeds. When using RNAST, it is necessary to use hardened and ground shaft shown in Article as outer ring
