I was able to find the part you referenced, National Oil Seal part number 474276, on an internet search. Please note that this is an oil seal, not a grease seal, and is intended for oil bath bearings.

We do offer a range of both types of seals, grease and oil, but I do not see an exact cross reference to the number 474276 and my contact at Redline trailer supply did not have a match either.

If you know your bearing numbers you can identify the correct seal with that information. The bearing part number should be stamped into the outer ring of the bearing. For example, if you type bearing number L44649 in the search box on our site you will see results that include the appropriate grease seal for that bearing, part # RG06-050.

You can also search by seal diameter using the link provided. According to my research the part 474276 you referenced has an outer diameter of 1.988 inches; you can use the link to identify seals with the same outer and inner dimensions. The best way is to use your bearing numbers.
