Expert Reply:

It looks like the National 471750 grease seal has an outer diameter of 1.983 inches and an inner diameter of 1.25 inches. The replacement grease seal that we offer is part # 34823. This is a double lip grease seal that is best suited for marine applications such as a boat trailer and it fits hubs that use the same bearing and race combination and spindle size that you mentioned.

If you also need new grease, I recommend picking up our LubriMatic Marine Trailer grease # L54FR which includes three - 3 oz cartridges and a compatible grease gun like the # L30100 for the cartridges if you need one.
