I bought it to replace the bearing for the motorcycle's wheel.
Because it was cheaply cheaper than a genuine product, I thought it would be overseas made (it was written in Taiwan made in comments), but I was relieved because it was made in Japan.
Purchased for exchanging bike wheel bearings. It was good because it was equivalent to genuine and it was cheap and could be purchased. It is not a conspicuous part, but reliability is essential, so I think that this product is no mistake.
According to the parts list of the motorcycle, the genuine product seems to be using a contactless seal product of C3 clearance. Since this is a contact seal type, I will try to make a black guy next time non-contact seal.
