Isn't the failure mode of most bearings more about mechanical grinding (against dirt, sand, whatever is hard and gets into the bearing) as it is corrosion?Ryanhttps://www.blogger.com/profile/15514653089603456867noreply@blogger.comtag:blogger.com,1999:blog-36151678.post-86088352477877622772009-02-08T18:36:00.000-08:002009-02-08T18:36:00.000-08:00I was always under the impression that hubs had to...I was always under the impression that hubs had to be repacked on Repack due to coaster brakes...?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-36151678.post-37047764004556561082009-02-08T13:08:00.000-08:002009-02-08T13:08:00.000-08:00@Feldy:http://www.youtube.com/watch?v=AIICLDgZFNU&...@Feldy:<BR/><BR/>http://www.youtube.com/watch?v=AIICLDgZFNU&feature=PlayList&p=CD067D632FCB7778&index=16Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-36151678.post-16794551730846402182009-02-05T22:39:00.000-08:002009-02-05T22:39:00.000-08:00Feldy, you never cease to amaze me.With your 80's-...Feldy, you never cease to amaze me.<BR/><BR/>With your 80's-themed geekiness, that is.<BR/><BR/>Fine, I'll go look up the density of steel...7.8g per cubic centimeter.<BR/><BR/>So there.Walthttps://www.blogger.com/profile/09156620599767391579noreply@blogger.comtag:blogger.com,1999:blog-36151678.post-86359116651800696242009-02-05T21:12:00.000-08:002009-02-05T21:12:00.000-08:00Highly entraining and educating.

I believe HYBRID ceramic bearings are only where the balls themselves are ceramic. They're an easy, relatively cheaper retrofit but then the existing races are still steel, and exposed to potential corrosion.<BR/><BR/>You're absolutely right about the economics of ceramic bearings; not enough return for the investment.Anonymousnoreply@blogger.com
