Thanks. The Timken 4739 looks very similar to the 8871 that I pulled off, with the exception that the 8871 has a flange to mate against the hub top surface.

I'm not a seal expert, but does a seal need to be bedded against some type of surface or can it "free float" for lack of a better word? The 8871 is bedded against the top surface of the hub via its flange and is 0.260" thick. The 9015S is bedded against the top of the race surface via its bottom surface and is 0.505" thick. The race top surface to hub top surface is ~0.340", so the Timken 4739 would be "free floating" and not bedded against any type of surface. Only the friction of the side walls would be holding it in place. I wonder if that would make it more prone to being out of square with the shaft, not sure.

I appreciate you looking into it, PJ.
