I wasn't able to cross-reference these numbers but if you're looking for new bearings/races and seals all you need to do is note the capacity or measure. The easiest method would be to crawl under the trailer and look for the axle tag on the beam. This should give an axle capacity which we can then use to find the bearings based off industry standards. For example, a 3,500 lb axle uses L68149 and L44649 bearings like what comes with the Hub Bearing Kit for Lippert, Dexter, and Al-Ko Axles part # BK2-100. The other option would be to take the hubs off the trailer and either read the part numbers off the old bearings or measure them with a dial caliper to the nearest thousandth of an inch. I have attached an article that goes over this process in more detail.
