Seal #2233TB. I bought these for my 2,250" boat spindle. Your drawing shows that the inner diameter is the same on both lips. That is not right. They are not the same. Looking at the outside surface of the seal, the first "wiper" lip measures approximately 2.31" (2-5/16") and doesn't even touch my spindle. The second inside edge measures about 2.188" (2-3/16") and fits my spindle nice and snugly like it should. If you use them on a 2-1/4" spindle, you only get a single lip seal, not two! They keep your grease inside, but the first "wiper" seal doesn't do anything for you. That is the whole reason for having a double lip - one to keep dirt out and the other to seal!Other than that I don't attribute any other cons to them.They look good and arrived quickly.Unfortunately they don't fit me so I'm sending them Moral of the story: ALWAYS measure your gaskets before installing them!Update: I added a star as returning it was quick and easy.I never like to leave bad reviews but felt like I should , as these seals aren't exactly easy to install and can seriously damage your bearings if they leak, not to mention the time it takes to get them. Maybe I just got a bad batch? Who knows. I h open, the supplier can check his inventory.
