The seal that comes with hub # 8-201-9UC3-EZ is a 10-10 seal. For a pair use # RG06-090. These seals have an inner diameter of 2.125 inches and an outer diameter of 3.376. They are used with E-Z Lube and Oil 5,200, 6,000 and 7,000 LB Axles. I have included a link to a video review of the seal for you.

I could not find a seal with the numbers you provided but if you have hub # 8-201-9UC3-EZ then the correct seals are # RG06-090.

There is a 10-36 seal, # RG06-070. This seal has an inner diameter of 2.250 inches and an outer diameter of 3.376 inches and is used on E-Z lube end axles. The difference is that the inner diameter of this seal is 2.250 inches and the 10-10 is 2.125 inches.

I have dexter 5200 lb axles on my boat trailer. EZ lube design 25580 and 15123 bearings the seals that came out of it appear to be 10-10 seals but the spindle at the seal area measures 2.25 does this make it a 10-36 and was it misbuilt?

How did you take that measurement? A precise measurement with a dial or digital caliper is really what is needed to determine accurately what seal should be used, out to 3 decimal places. If it was taken with a dial caliper and it does measure 2.250, then a 10-36 is needed. There are two bearing kits with that bearing combo of 15123/25580. One has a 10-10 and the other a 10-36. A precise measurement of that spindle or 100% positive ID of the seal is the best way to determine needed seal. It would be very difficult to force a 10-10 onto a 2.250 spindle.
