I have a set of Misumi linear rails and bearing blocks and IMO the quality is noticeably worse than my THK and IKO brand rails and blocks. Specifically, the finish quality is inferior and the linear motion does not feel as smooth. I have no way of knowing if this is consistent across all Misumi parts but... judging by the price differences... I think that THK and IKO are in a different league.
I should add that I don't consider the Misumi rails to be poor quality or anything like that. If I hadn't seen my THK and IKO rails then I would have no complaints with the Misumi stuff. For what I am using them for, it probably won't make a difference.
