Review on Koyo B 912 Bearing Complement Rotational by Matt Welch

I needed two replacement bearings in Koyo B-912 sizes. I couldn't find it locally so I decided to look online. There are similar bearings on different sites, but these are chinese junk that wears out quickly. I knew Revain had the Koyo brand - priced a lot cheaper than other sites - so I ordered two. The bearings arrived as expected and I installed them with no problems.
