Question:

I was unable to locate any cross-reference information for the National 470316 grease seal you mentioned. I spoke with my contact at Redneck Trailer Supply, where we get most of our bearings and seals from, and he came up empty handed, as well.

This is not to say that I cannot find a replacement for you, though. Take some good, accurate measurements of the outside diameter of your existing seal, and the diameter of the surface of the spindle where the seal would ride, which is dimension B on the diagram I provided. Unfortunately, a ruler or tape measure will not be accurate enough, you will need a dial or digital caliper.

If you would respond with this information, we can most likely get some seals for you.
