I ordered a set of Timken hubs and when they arrived they came in an SKF box. So, that would confirm my suspicion that they are the same hubs as those NAPA sells. I put a micrometer on them and verified that they are 9mm thick at the flange.

I had them pressed onto the knuckles and cryo'd both assemblies (hub,bearing,knuckle). Ran them last weekend in an enduro and will run another 4 race weekends or so then replace.

I'm thinking of sending them to a metalurgy lab when I pull them off to get an analysis done to find out how much fatigue has occured. I am interested to know if the cryo makes a huge difference. Anyone have a hookup to a metalurgy lab who might want to donate an analysis for the sake of research?
