MR24378-2RS Ceramic Bearing Sealed 24x37x8 Metric

Replaced all the hub bearings on my bicycle and these rolls faster and smoother than the stockers.

The bearings in this order and in the previous order are sized just as described in the respective product descriptions. Future orders will occur at the end of their service lives. This review was marked down to four stars because of the lack of labeling.
Regarding these future orders, I'll ensure to keep the new and old bearings separate because there is no information label on the packaging. Additionally, there is no information/marking either on the outer race body or imprinted on the rubber seal(s) as may be seen on other-brand bearings. Without due diligence, a new regular and ceramic hybrid bearing of the same size could be mistakenly switched as there is no visual cue to the user. Sure would be convenient to have some sort of labeling on the bearings themselves, perhaps maybe a different color seal. This issue will not prevent me from ordering again. I'll just have to be careful.
Sincerely,
