Here is the layout as it came out of my wheel, Demonstrated for just one side here as the other two bearings for the other side are elsewhere-



Outer spacer-seal-bearing-bearing-internal spacer-bearing-bearing-seal-outer spacer.

And yes it checks out as 25x42x9. Most of the trade references should properly be -2RS (2 rubber seals) or -2RS1 for big makers like SKF. They are also seemingly the same as a 6905-2RS. I think Timken has them listed as such but I know SKF does. Markings indicate C&U Bearings-“the largest bearing producer in China and one of the top 8 bearing manufacturers worldwide...” seemed to be fairly standard deep groove ball bearings, didn’t outwardly appear cheap and even after pounding one of the races with a flathead screwdriver to get it out it still spun fairly well, though the rubber seal was shot. Not the best, but far from the worst.
Of note-very little evidence of ANY lubricant used for install. Aside from the internal grease in the bearings everything else was VERY dry.



Bearings were SMASHED into the center spacer and then into each other. Absolutely zero movement until I got one to budge, then everything started spinning.
