Wheel Bearing Seal Size

[Vulcan]

I have a 2018 Aspen Trail 1900rb with dual axles. Preparing to inspect and repack bearings. Would like to order bearing seals prior to getting started (being optimistic that new bearings won't be needed). Is there a resource for camper trailer bearing seal sizes?

Number on the seal will tell you which one you have. They are available at just about any auto parts store.
