Question:

Looking to replace the inner/outer bearing on a boat trailer. I have the outer bearing 09067, race 09195 and seal #16743 - can those numbers help determine the Inner seal # - that, I do not have

Sometimes, on common wheel bearing kits you can find the inner or outer bearing you need if you have just one of the bearings and the grease seal. The issue with yours is the Timken outer bearing 09067 and seal 16743 you have are not popular sizes that would allow us to give you the correct inner bearing.

What that means is you need to use digital caliper and measure your spindle to the thousandths of an inch where the inner bearing rides; you can use the photo I've attached to see exactly where you need to measure. Doing this will allow you to find the correct bearing you need.

I have attached a link to our entire selection of bearings, and once you find the inner diameter you need, you can use the "Inner Diameter" facet on the page to find your exact bearing, or if you let me know what it is I would be happy to take a look for you.
