I bought it for replacement from the manufacturer complete assembly. The NHK bearing has a feeling that it is crisp every few centimeters at the time of opening check. I am sorry to say that it can not be helped because it is JIS grade 0. If you replace grease with AZ BGR - 006 with less than half of original grease, both shields are very heavy. I wonder how to install the shield ... .... I wish I could use it without changing the grease in this case.

Ceramic speed, TNI, cruising speed and time even when compared with the ceramic base bearings, such as Enduro is not comparable. However, once after the grease of flipping through seal spin encapsulation, processing the seal corresponding to the inner hub. First by the grease is changed is there is a feeling that hit the Kotsunkotsun, but it began to furiously rotation in about 100 km. Although you really say, it is sufficient stainless steel bearing of a Japanese company if wheel to use the cartridge to the hub.

There are three incisions on one side of the inner and the outer. As far as this application is concerned, it can be used because one side does not touch anything. But this is a serious flaw. By the way, there were no such defects in the former NSK and Nankai Seiko's equivalent.
