We have a bearing thats nearly roasted in the natural gas furnace. Its a
NMB 608Z, near as I can figure this is the same as a 8x22x7mm bearing. Its
for the exhaust fan near a lot of heat. I found tons of inline skate
bearings that are 8x22x7mm, now the big question is does anybody have links
or info regarding whether I should go ceramic,stainless, or just the
cheapest steel ones I can get. after application data ? so I can wrap my
head around this stuff. Thanks.
